releasing the volume switch checks the volume setting. Your display will show “VOLUME_ _”
and a number value (0-15). Press and hold the left side to decrease the volume. The number
value scrolls up or down to your desired level. The Volume rocker switch also controls the
volume level of the public address (PA) and external radio speaker (Ex Rd) options when they
are enabled. The display window shows “PA VOL _ _” when public address is on and the
Volume rocker switch is pressed.
• Dim Button — The DIM button is used to control the brightness of the display and button
backlighting. When you turn on the system, the display comes on at the brightness level it was
on before the system was last turned off. Press the DIM button once to reduce the brightness of
the display to medium level and twice for low brightness level. Press the DIM button a third time
to turn the display and button backlighting off. This is called the “surveillance” mode.
• Home Button — The Home button is used for restoring preprogrammed mode, establishing
programmed mode, selecting programming entries, etc. Press the Home button to go to the
radio’s preprogrammed “home” mode. On the W7 models, you may use the Home button
instead of Mode switch to change modes. Hold the Home button until a beep sounds to enter
the configuration state. The display shows an entry prompt. Use the keypad to enter your new
mode choice and press the Home button again. Your mode is now changed without scrolling.
• Select Button — The Sel button is used to configure radio options.
• Option Buttons — The option buttons are used for turning options on and off, such as Phone,
Scan, Emergency Call, and Secure.

• Display — The vacuum fluorescent (VF) display’s primary function is to display mode numbers,
mode names, volume level, and the status of options. It also functions as an on-off indicator for
the entire system and plays an integral role in the operator’s reconfiguration of options. The
display is 8 characters on W4, W5, and W7 models; 11 characters on the W9 model.
• XMIT and BUSY Indicators — The XMIT indicator lights when the radio is transmitting. The
BUSY indicator lights when the selected channel is busy.
• Scan Indicators — When scan operation detects activity on a non-priority (NON-PRI) channel,
the NON-PRI indicator light comes on. Activity on a second priority channel causes the priority
(PRI) indicator to light. First priority channel activity causes PRI to flash.
• 12-Button Keypad (W7 and W9) — The keypad is used to change the status of options and for
entering numbers. Several keys serve multiple functions. See the ASTRO XTL 5000 Digital
User’s Guide for a complete description of keypad operation.

Chapter 2Basic Maintenance
2.1Introduction
This section of the manual describes preventive maintenance, handling precautions, and some basic
repair procedures and techniques. Each of these topics provides information vital to the successful
operation and maintenance of your rad io.
NOTE: For board- and component-level repair of the radio, refer to the Detailed Service Manual (see
”Related Publications” on page xii).
2.2Preventive Maintenance
Radios are shipped from the factory with a worst-case frequency error of ±500 Hz for 700–800 MHz.
These specifications are tighter than the more stringent FCC requirements of ±1.5 ppm for the 700–
800 MHz bands. For radios that have been in storage for over six months from the factory ship date,
the reference oscillator should be checked when the radio is initially deployed to the field. It is
strongly recommended that the reference oscillator be checked every time the radio is serviced or at
least once a year, whichever comes first. The crystal contained in the reference oscillator naturally
drifts over time due to its aging characteristic. Periodic (annual) adjustment of the reference oscillator
is important for proper radio operation. Improper adjustment can result in both poor performance and
interference with other users operating on adjacent channels.
2.2.1Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. A detailed inspection of the interior electronic circuitry is not needed.
2.2.2Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the radio. External surfaces include the control
head and radio chassis. These surfaces should be cleaned whenever a periodic visual inspection
reveals the presence of smudges, grease, and/or grime. Internal surfaces should be cleaned only
when the radio is disassembled for servicing or repair.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water. T he only factory recommended liquid for cleaning the printed circuit
boards and their components is isopropyl alcohol (70% by volume).
The effects of certain chemicals and their vapors can have harmful results on
!
C a u t i o n
certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should
be avoided.
2.2.2.1 Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled
brush to work all loose dirt away from the radio. A soft, absorbent, lint-free cloth or tissue should be
used to remove the solution and dry the radio. Make sure that no water remains entrapped near the
connectors, cracks, or crevices.
Page 32
2-2Basic Maintenance: Handling Precautions
2.2.2.2 Cleaning Internal Circuit Boards and Components
Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded
or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged
material out and away from the inside of the radio. Be careful not to break off electrical components.
Alcohol is a high-wetting liquid and can carry contamination into unwanted places if an excessive
quantity is used. Make sure that controls or tunable components are not soaked with the liquid. Do
not use high-pressure air to hasten the drying process, since this could cause the liquid to puddle
and collect in unwanted places.
Upon completion of the cleaning process, use a soft, absorbent, lint-free cloth to dry the area. Do not
brush or apply any isopropyl alcohol to any plastic parts.
NOTE: Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).
2.2.3General Radio Care and Handling Precautions
• Avoid physical abuse: do not pound, drop, or throw the radio. It may damage exposed parts
such as controls and connectors.
• Do not connect accessories other than Motorola compatible equipment as they may damage
the radio.
• The use of any mini-UHF adaptor not listed in this manual can damage the RF antenna
connector and lead to radio failure and may void the warranty.
• Operating the radio without an antenna cable attached may lead to radio failure and may void
the warranty.
2.2.4RF Power Amplifier (RF PA) Heatsinking
You should never transmit unless the printed-circuit board (PCB) DC/RF clips and internal screws
are installed in the chassis. Doing so can result in immediate failure of RF PA devices or greatly
reduced RF PA device life. You also can transmit for short periods with the chassis eliminator if it is
used properly.
2.3Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices,
are used in this family of radios. While the attributes of these devices are many, their characteristics
make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special
precautions must be taken to prevent device damage during disassembly, troubleshooting, and
repair. Handling precautions are mandatory for this radio, and are especially important in lowhumidity conditions. DO NOT attempt to disassemble the radio without observing the following
handling precautions:
• Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
• Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose-hanging neckties.
• Store and transport all static-sensitive devices in ESD-protective containers.
• Disconnect all power from the unit before ESD-sensitive components are removed or inserted
unless otherwise noted.
• Use a static-safeguarded workstation, through the use of an anti-static kit (Motorola part
number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table
mat and a static-control floor mat.

Basic Maintenance: Handling Precautions2-3
NOTE:Be sure that the table and floor mats are properly grounded.
When these items are not readily available, observing the following techniques will minimize the
chance of damage:
• If a static-sensitive device is to be temporarily set down, use a conductive surface for
placement of the device.
• Make skin contact with a conductive work surface first and maintain this contact when the
device is set down or picked up.
• Always wear a conductive wrist strap when servicing this equipment. The Motorola part number
for a replacement wrist strap that connects to the table mat is 42-80385A59.

3.1Introduction
The ASTRO XTL 5000 radio combines the controller and RF sections into a single board and
contains three modules: a daughtercard, RX VCO module, and TX VCO module. It is important to
correctly identify the malfunctioning region before replacing expensive modules. To assist with radio
repair, descriptions of the sections contained on the XTL 5000 uniboard are listed below.
3.2General Overview
The XTL 5000 radios are wideband, synthesized, fixed-tuned radios and are available with 700 and
800 MHz bands. All XTL 5000 radios are capable of both analog operation (12.5 kHz, 20 kHz, and
25 kHz bandwidths) and ASTRO mode operation (12.5 kHz bandwidth).
The XTL 5000 radios contain the following assemblies and sections:
• Control-Head Assembly (Dash- or Remote-Mount)—is connected directly to the front of the
transceiver or remotely by the interconnect board and control cable. This assembly contains a
vacuum fluorescent (VF) display, VF driver, microprocessor and serial bus interface.
• Power Amplifier (PA) section—contains the antenna switch, directional coupler/ detector, and
amplifier(s).
• Front-End Receiver section—contains the preselector, low-noise amplifier (LNA), and mixer.
• IF section—contains the receiver intermediate-frequency (IF) amplifier/filter and the digital
receiver back-end integrated circuit (IC).
• Frequency Generation section—contains the synthesizer, voltage controlled oscillators (VCOs),
reference oscillator, and receive and transmit buffers.
• Controller section—combines a VOCON board and a Command board, into a single section,
and contains the following elements:
- Voltage regulators, data communication circuitry (RS232, USB, and SB9600)
- Front connector interface for control heads and remote-mount interconnect boards (I.B)
- Rear connector for additional accessories
- DC power-in plug

3.3Controller Section
3.3.1Introduction
The XTL 5000 radio is primarily a uniboard design, consisting of isolated topside and bottomside
controller sections and various RF sections. The controller section will be discussed here in basic
terms, to assist in the overall understanding of what is contained in the controller section, and a
simplified purpose of its elemental parts. Some limited warnings and recommendations are offered
for prevention of common repair-induced damage.
The controller section combines the elements of a VOCON board, with the elements of a command
board. The controller section also contains a daughtercard module. We distinguish the entire
controller section into 2 parts: the "daughtercard module" and the "surrounding controller region".
3.3.2Location
The controller section is located on the far side of the board, with critical parts arranged on the top
and bottom sides of the uniboard. (see
controller section).
Figure 3-1 below, with component-filled areas denoting
SIDE1SIDE2
Figure 3-1. Controller Sections
Troubleshooting of the controller section usually requires the removal of the
!
C a u t i o n
uniboard from the chassis. Whenever this board is removed, any
transmitting of the RF section, whether intentional or accidental (trunking
affiliation), can cause permanent destruction or degradation of various RF
components. Such damage may not be visually noticeable, but can impact
the radios performance and reliabil ity.
3.4Daughtercard Module
This module contains primarily three parts: microprocessor, FLASH IC, and SRAM IC.
NOTE: The three parts on the daughtercard module are highly susceptible to ESD and moisture
damage. Extreme care is advised.

Basic Theory of Operation: Surrounding Controller Region3-3
3.4.1Microprocessor
The microprocessor consists of an MCORE-based controller and a DSP that communicates with the
memory ICs via a 16-bit data bus. It also communicates to peripheral ICs on the main board via an
SSI and SPI bus. This microprocessor contains a fixed amount of one-time programmable ROM and
a small section of RAM. However, the microprocessor does not contain the radio software setting as
programmed in the Customer Programming Software (CPS) or the firmware as installed at the
factory. The only purpose of this IC is for interpretation and processing of the content inside the
FLASH IC. Therefore, this part may be replaced as is without the need to reflash the radio.
There are six clocks supplied to the daughtercard, a 16.8 MHz master clock (CKIH), a 32 kHz realtime clock (CK IL), a 20 kHz RX frame-sync clock, a 48 kHz TX frame -sync clo ck, a 1 .2 MHz RX data
clock, and a 2.4 MHz TX data clock. The microprocessor also generates the digital audio bus clocks:
a 512 kHz data clock and an 8 kHz frame-sync clock.
3.4.2FLASH IC
The FLASH IC is the firmware storage IC. Programming this IC is accomplished using one of three
input paths:
• 2-wire RS232 directly from a computer's serial port to the radio’s rear connector data cable,
HKN6160
• 2-wire RS232 through an HKN6155 programming cable at the control head’s 10-pin
microphone port
• 2-wire RS232 through an HKN6155 programming cable at the Remote Mount Interconnect
board’s 10-pin flash port.

part is removed, the radio must be reflashed and retuned. This is because the FLASH IC must
be hard-boot loaded at the factory to allow the programming of a unique file.
3.4.3SRAM IC
The SRAM IC is only used by the microprocessor to perform its memory operations and is not
upgradeable to a larger SRAM IC.
3.5Surrounding Controller Region
3.5.1Introduction
The surrounding controller region contains the regulated power, audio, and data translation
hardware.
This hardware allows a computer to program the radio's features, maintain an active control of the
RF sections, and make necessary mode and audio adjustments as related to feedback from a
control head device.

June 13, 20036881096C73-O
3-4Basic Theory of Operation: Surrounding Controller Region
NOTE: A control head is not necessary for the function of the radio (in special application
configurations), but the controller section is critical for the RF sections to function. This is an
important point since repairs and troubleshooting of the RF sections usually requires that the
controller section is operating correctly.
3.5.2Voltage Regulation
The uniboard contains the following voltage regulators: 9 V, 5 V , 3V, 2.85 V, 1.85 V, and 1.55 V.
The radio’s A+ supply is regulated down to additional supplies for various blocks (frequency
generation unit (FGU), receiver, transmitter power amplifier, and controller). Specifically, A+ is used
to regulate three separate 9.3-volt supplies, one for the FGU and receiver circuitry, one for the
transmitter power amplifier circuitry, and one for the controller sections.
• The FGU and receiver circuitry use the 9.3-volt supply to further regulate a common 5-volt
supply and two separate 3-volt supplies, one for the FGU and one for the Abacus III IC.
• The transmitter power amplifier uses its 9.3-volt supply directly for its pre-amplifier and to a 3volt supply for most of the ALC (automatic level control).
• The controller uses the 9.3-volt supply to power the microphone, part of a RS232 translator,
and to provide voltage to the 5-volt regulator, which supplies the 2.85 V, 1.85 V, and 1.55 V
supplies.
- The 2.85-volt regulator supplies most of the digital logic circuitry on the controller, as well as
the I/O of the microprocessor.
- The 1.85-volt regulator supplies the FLASH and SRAM circuitry.
- The 1.55-volt regulator supplies the core of the microprocessor.
3.5.3Emergency
Circuity exists to support emegency switch operation. While the radio is ON, emergency can be
activated to alert dispatch.
NOTE: This feature is either visual or can be set to covert, and is programmable through the CPS
(customer programming software). This functionality is dependent on CPS version and
customer demand for feature availability.
3.5.4Front and Rear Connectors
The surrounding controller section contains the front and rear connections to allow interfacing with
existing and future accessories.
These custom connectors are optimized to meet voltage and current requirements for existing
accessories and for the compatible flexes that are used with the XTL 5000 radio.
NOTE: It is not recommended to insert non-Motorola parts or flexes into these connectors.
Page 39
Basic Theory of Operation: Surrounding Controller Region3-5
3.5.4.1 Audio
The audio circuitry of the controller section contains the following:
•Audio PA
• Codec
• MIC Audio
• DSP controlled EEPOTS
• AUX RX, AUX TX, and external speaker paths
• FILT audio.
This allows interfacing to the existing accessories made by Motorola, such as VRS, SIREN, and
Consolette. It also allows for select compatibility with aftermarket modems.
3.5.4.2 Program Cable
If the programming cable is used with a standard legacy control head, circuitry found in the controller
section provides the voltage-translated boot RX and boot TX communication paths, as well as the
cable-detection circuit.
3.5.4.3 SB9600
Just as on many Motorola products, an SB9600 communication bus exists on the XTL 5000 radio.
Hence, many Motorola SB9600 accessories are compatible with the radio. These lines include
BUS+, BUS-, Busy, and RESET. These lines are available at connectors J5 and J6.
3.5.4.4 VIP
VIP-IN and VIP-OUT lines are available at the front and two VIP-out lines are located at the rear.
Their purpose is to drive relays to control external logical devices, or to logically communicate
directly to the XTL 5000 microprocessor. Their most versatile usage is in conjunction with a DEK, but
this is not mandatory.
NOTE: Please see the VIP section of the ASTRO XTL 5000 700–800 MHz Digital Portable Radio
Detailed Service Manual for configurations and voltage level requirements.
3.5.4.5 RS232
UART_A can be selected as a standard 4-wire RS232 or 4-wire USB slave device. The UART_B is
defaulted to use SB9600 lines so that all legacy control heads and SB9600 accessories are
compatible with the radio.
3.5.4.6 One-Wire
One-wire technology is embedded in the radio for future compatibility with upcoming smart
accessories.

3-6Basic Theory of Operation: Analog Mode of Operation
3.6An alog Mode of Operation
3.6.1Receive Operation
When the radio is receiving, the signal comes from the antenna through the RF PA output network
located in the power amplifier section to the front-end receiver assembly. The signal is then filtered,
amplified, and mixed with the first local oscillator signal generated by the receiver voltage controlled
oscillator (VCO). The resulting intermediate-frequency (IF) signal is fed to the IF circuitry where it is
again filtered and amplified. This amplified signal is passed to the Abacus III IC where it is mixed with
the second local oscillator to create the second IF at 2.25 MHz. The analog IF is processed by an
analog-to-digital (A/D) converter located within the digital back-end IC, where it is converted to a
digital bit stream and decimated down to an I/Q digital sample. This digital signal is then passed on
to the DSP, where filtering and discrimination are performed in the software. For a voice signal, the
DSP routes the digital voice data to the Codec for conversion to an analog signal. The signal passes
through a Log Pot to the audio power amplifier, which drives the speaker. For signaling information,
the DSP decodes the message and passes it to the microcom put er.
3.6.2Transmit Operation
When the radio is transmitting, microphone audio is passed to the gain control, and then to the
Codec, where the signal is digitized. The Codec passes digital data to the DSP, where pre-emphasis
and low-pass (splatter) filtering is done. The DSP returns this signal to the Codec and the signal is
then passed to a digital-to-analog (DAC) converter where it is reconverted into an analog signal. The
signal is then passed through a switched capacitor filter IC and then to the synthesizer IC as a
modulation signal for the transmitter voltage controlled oscillators. Also, transmitted signaling
information is accepted by the DSP from the microcomputer, coded appropriately, and passed to the
Codec, which handles it the same as a voice signal. Modulation information is passed to the
synthesizer along the modulation line. A modulated carrier is provided to the RF power amplifier,
which transmits the signal under dynamic power control.
3.7ASTRO Mode of Operation
In the ASTRO mode (digital mode) of operation, the transmitted or received signal is limited to a
discrete set of deviation levels, instead of continuously varying. The receiver handles an ASTROmode signal identically to an analog-mode signal up to the point where the DSP decodes the
received data.
In the ASTRO receive mode, the DSP uses a specifically defined algorithm to recover information.
In the ASTRO transmit mode, microphone audio is processed the same as an analog mode with the
exception of the algorithm the DSP uses to encode the information. This algorithm will result in
deviation levels that are limited to discrete levels.
3.8Control Head Assembly
3.8.1Dis play (W4, W5, and W7 Control Heads)
The W4, W5, and W7 control-head assemblies have an 8-character, alphanumeric, vacuum
fluorescent display. The anodes and the grids operate at approximately 34 Vdc when on and 0 Vdc
when off. The filament operates at approximately 24 Vrms. The voltage for the display is generated
by a fixed-frequency, variable duty-cycle controlled “flyback” voltage converter. The switching
frequency is approximately 210 kHz. The internal microprocessor controls the voltage converter,
which provides approximately 3.7 Vdc to the vacuum fluorescent (VF) driver and approximately
2.4 Vrms to the VF display.
June 11, 20036881096C73-O
Page 41
Basic Theory of Operation: Control Head Assembly3-7
3.8.2Display (W9 Control Head)
The W9 control-head assembly has an 11-character, alphanumeric, vacuum fluorescent display. It
needs three separate voltages to operate: the cathode needs 35 V to accelerate electrons to the
anode; the grid needs 40 V to totally shut off current flow; the filament needs 3.8 Vrms at 80 mA.
These voltages are obtained from the transformer on the display controller board.
3.8.3Vacuum Fluorescent (VF) Display Driver
This VF display driver receives ASCII data from the controller section of the main board, decodes it
into display data, and then scans the display with the data. Once properly loaded into the display,
data is refreshed without any further processor action. The display driver is periodically reset by the
actions of transistors that watch the clock line from the microprocessor to the display driver. When
the clock line is held low for more than 600 ms, the display driver resets and new display data
follows.
3.8.4Vacuum Fluorescent (VF) Voltage Source (W9)
Voltage for the VF display is generated by a fixed frequency, variable-duty cycle-driven, flyback
voltage converter. An emitter-coupled astable multivibrator runs at approximately 150 kHz. The
square-wave output from this circuit is integrated to form a triangle that is applied to the non-inverting
input of half an IC.
During start up, the inverting input is biased at 3.7 V. A transistor is on while the non-inverting input
voltage is below 3.7 V. This allows current to flow in a transformer, building a magnetic field. When
the triangle wave exceeds 3.7 V, the transistor turns off and the magnetic field collapses, inducing
negative current in the transformer.
This current flow charges two capacitors. As the voltage on one of the capacitors increases beyond
35 V, a diode begins to conduct, pulling the integrated circuit’s inverting input below 3.7 V. This
decreases the cycle time to produce the 35 V. The 41-volt supply is not regulated, but it tracks the
35-volt supply.
Similarly, the AC supply for VF filament is not regulated, but is controlled to within one volt by an
inductor on the display board.
3.8.5Controls and Indicators
The control head assembly processes all the keypad (button) inputs and visual indicators through
the microprocessor. Some of the buttons double as function keys for radio options. All buttons are
backlit to allow operation in low light. Refer to
Descriptions” on page 1-2
) for functional descriptions of each control switch, button, or indicator.
3.8.6Status LEDs
These LEDs are driven by the display driver as though they were decimal points on the VF display.
Level shifting transistors are required for this since the display driver uses 39 Vdc for control signals.
3.8.7Backlight LEDs
The microprocessor operates the backlight LEDs. A transistor supplies base current to the individual
LED driver transistors. The driver transistors act as constant current sources to the LEDs. Some
backlight LEDs are connected to a thermistor. This circuit allows more current to flow through these
LEDs at room temperature and reduces current as the temperature rises.

3-8Basic Theory of Operation: Control Head Assembly
3.8.8Vehicle Interface Port (VIP)
3.8.8.1 Remote-Mount
The VIPs allow the control head to operate outside circuits and to receive inputs from outside the
control head. There are three VIP outputs that are used for the W9 control head and two VIP outputs
for the W3, W4, W%, and W7 control heads. There are also three VIP inputs that accept inputs from
switches. See the cable kit section for typical connections of VIP input switches and VIP output
relays.
The VIP output pins are located on the back of the control head below the area labeled “VIP.” These
connections are used to control relays. One end of the relay should be connected to switched B+,
while the other side is connected to a software-controlled on/off switch inside the control head. The
relay can be normally on or normally off depending on how the VIP outputs are configured. The
function of these VIP outputs can be defined by field programming the radio. Typical applications for
VIP outputs are external horn/lights alarm and horn ring transfer relay control.
3.8.8.2 Dash-Mount
The VIP outputs are driven by a serial-to-parallel shift register. The output transistors are capable of
sourcing 300mA current. Primarily, these transistors control external relays. The relay is connected
between the collector and switched B+.
Each VIP input transistor is connected to a dedicated input port through transistors used for input
protection. These VIP inputs are connected to ground with either normally open or normally closed
switches.
3.8.9Control-Head Power Supplies
This section describes the control-head power supply operation.
3.8.9.1 W3 Control Head
W3 control heads supply power to the switched B (SWB+) line through a P-channel power MOSFET
from the HLN6885 interface board only.
3.8.9.2 W4 Control Head
For W4 control heads, power to SWB+ is supplied by a mechanical switch on the volume control
knob. If the ignition line option is used, power to the switch comes directly from the ignition wire
instead of A+.
3.8.9.3 W5, W7, W9 Control Heads
SWB+ is supplied from A+ through an N-channel power MOSFET driven by the Serial Input/Output
(SIO) IC in the legacy control heads. SWB+ supplies power to the accessories, the VF display, the 5volt regulator, and the power-control line for the main board for all other voltage regulators on the
main board. The SIO IC monitors the condition of the power switch and the ignition switch to
determine the on/off stat e of the radio.
3.8.10 Ignition Sense Circuits
A transistor senses the vehicle ignition’s state, disabling the radio when the ignition is off. For
negative-ground systems, the orange lead for remote-mount radios and the red lead for dash-mount
radios is typically connected to the fuse box (+12 V).

Page 43
Basic Theory of Operation: Radio-Frequency Power Amplifier (RF PA) and Output Network (ON )3-9
3.9Radio-Frequency Power Amplifier (RF PA) and Output Network
(ON)
The RF PA is a three-stage power amplifier consisting of discrete LDMOS transistors:
• Controlled stage
• Drive r stag e
• Final stage
The RF PA is followed by the ON section consisting of discrete circuitry with the following functions:
• Antenna switch
• Harmonic Filter
• Power Detector
3.9.1G ain Stages
The controlled stage consists of a two-stage, integrated amplifier with external matching which
amplifies the input signal from the VCO buffer and provides drive to the driver stage. Power is
controlled via gate bias to both internal stages and drain bias is supplied via K9.1V. The drive stage
has a fixed gate bias and drain bias is supplied by the A+ (battery) voltage. The driver stage drives
the final stage consisting of two transistors operating in parallel. Both devices have separate, fixed
gate biases and their drain biases are supplied by the A+ voltage. The output of the final stage feeds
the antenna switch which routes the RF PA to the harmonic filter/power detector/antenna and
isolates the RX front-end in transmit mode. Antenna switch routes antenna/power detector/harmonic
filter to RX and isolates TX in RX mode. Mode is determined via K9.1V. The harmonic filter is a lowpass filter that attenuates harmonics generated by the RF PA in transmit mode and provides
additional receive selectivity in receive mode.
3.9.2Power Control
Power is regulated by an automatic-level control (ALC) circuit. The transmitter ALC consists of a
distributed power detector with a detection diode, buffer/amplifier, digital-to-analog converter (DAC),
and loop integrator. During transmission, the RF PA gain and output power is adjusted by a control
voltage. The power detector senses incident power transferred to the antenna via a directional
coupler whose signal is converted to a DC voltage by the detection diode. This DC voltage is
buffered/amplified and then added to the DAC voltage which is then compared to a fixed voltage
reference. The carrier power level is set tby adjusting the DAC voltage while monitoring the output
power, which is saved tin radio memory.
3.9.3Circuit Protection
RF PA final-stage drain current, RF PA final-stage temeperature, RF PA control voltage, and battery
voltage are sensed by the power-control circuitry. If a fault condition is detected, the control voltage
is reduced, which cuts back the output power to a level that is safe for the particular conditions.
3.9.4DC Interconnect
The DC connector at the edge of the board carries the A+ supply for the entire board. This supply is
routed directly to the controller and transmitter circuitry for both direct supply and regulating
additional supplies. The radio chassis is grounded through the PCB screws and also via direct
contact to the board. The control head receives the A+ supply through the 50-pin flex connector.

3-10Basic Theory of Operation: 700–800 Receiver Overview
3.10700–800 Receiver Overview
The receiver circuits primary duties are to detect, filter, amplify, and demodulate RF signals in the
presence of strong interfering noise and unintended signals. The receiver is broken down into the
following blocks:
• Front-end (preselector and LNA)
•Mixer
•IF
• Back-end IC
3.10.1 Receiver Front-End
The 700–800 MHz receiver front-end operates in two bands. The primary function of the front-end is
to optimize image rejection and selectivity while providing the first conversion. The front-end uses
ceramic filter technology and includes a wideband, monolithic amplifier. The first filter is a dual
switched filter that reduces the image frequency response and limits some of the out-of-band
interference. The second filter following the monolithic Low Noise Amplifier (LNA) provides additional
image rejection.
3.10.2 Mixer
The signal is then fed to the monolithic Mixer IC where it is down converted to an IF of 73.35 MHz.
The mixer is designed to provide low conversion loss and high intermodulation performance. The
mixer is driven by the receiver injection buffer, a two-stage discrete IC design used with the receiver
VCO to efficiently drive the mixer over a wide temperature range with minimum power variation. The
injection buffer provides 15 dBm to the mixer. The VCO performs low-side injection for the 800 MHz
band and high-side Injection for the 700 MHz band. The design maintains temperature stability, low
insertion loss, and high out-of-band rejection.
3.10.3 IF Circuitry
The crystal filters provide IF selectivity and out-of-band signal protection to the back-end IC. Two 2pole crystal filters centered at 73.35 MHz that are isolated from one another by a stable, moderate
gain amplifier are used to meet the receiver specifications for gain, close-in intermodulation
rejection, adjacent-channel selectivity, and second-image rejection.
3.10.4 Abacus III Back-End
The output of the IF circuit is fed directly to the Abacus III digital back-end IC. The ABACUS III is an
IC with a variable-bandwidth bandpass Sigma-Delta architecture. It is capable of down-converting
analog as well as digital RF protocols into a baseband signal transmitted on the Synchronous Serial
Interface (SSI) bus. The Abacus III IC converts the 73.35 MHz signal from the IF section down to
2.25 MHz using a second LO frequency of 71.1 MHz or 75.6 MHz. The second LO VCO is tuned to
71.1 MHz (low side) or 75.6 MHz (high side injection). The choice of frequency depends on known
spurious interference related to the programmed received frequency.

Abacus III digital back-end IC and to the controller section. The synthesizer turns on one of the four
VCOs (determined by mode and band of operation) and tunes it to the receiver (RX) local oscillator
(LO) or transmitter (TX) carrier frequency.
The voltage-controlled oscillator (VCO) module employs a Colpitts configuration with two bipolar
stages in a common-base, common-collector configuration. The LC tank circuit’s capacitive portion
consists of a varactor diode, coupling capacitor and a laser-trimmed capacitor for frequency
adjustment. The inductive portion consists of microstrip transmission line resonators for TX VCO and
coaxial resonators for RX VCO. Tuning is performed by the module manufacturer and is not field
adjustable. The varactor changes the oscillator frequency when the DC voltage of the steering line
changes. The output of the common base is coupled to the second transistor for impedance
buffering, and its output is coupled to respective TX/RX buffer amplifiers.
In TX mode, the transmitter VCO output is coupled to a three-stage buffer before being injected into
the power amplifier (see
on page 3-9
). In RX mode, the receiver VCO output is buffered and amplified with a two-stage
“3.9 Radio-Frequency Power Amplifier (RF PA) and Output Network (ON)”
transistor/microwave monolithic IC (MMIC) circuit. The output of the first-stage transistor is split into
two paths. One path feeds back to the synthesizer prescaler; the other path is injected into the
second-stage MMIC. The output of the MMIC provides the proper signal level for the LO port of the
RX front-end mixer (see
“3.10 700–800 Receiver Overview” on page 3-10).
The super filter supplies the voltage to the first two stages of the TX buffer and to the first-stage
transistor of the RX buffer/amplifier. The voltage for the third stage of the TX buffer is supplied by a
keyed 9.1 V source to conserve current drain while the radio is receiving. The second stage MMIC of
the RX buffer/amplifier is supplied by a 9.3 V regulator.

6.4.4Reference Oscillator Alignment
Radios are shipped from the factory with a worst-case frequency error of ±500 Hz for 700–800 MHz.
These specifications are tighter than the more stringent FCC requirements of ±1.5 ppm for the 700–
800 MHz bands.
For radios that have been in storage for over six months from the factory ship date, the reference
oscillator should be checked when the radio is initially deployed to the field. It is strongly
recommended that the reference oscillator be checked every time the radio is serviced or at least
once a year, whichever comes first.
The crystal contained in the reference oscillator naturally drifts over time due to its aging
characteristic. Periodic (annual) adjustment of the reference oscillator is important for proper radio
operation.
Improper adjustment can result in both poor performance and interference with other users operating
on adjacent channels.

6.4.7Tx Current Limit
NOTE: This alignment is required after replacing (or servicing) the transceiver board or after there
has been a change in the CPS-adjustable power level.
The Tx Current Limit alignment procedure tunes the Tx current-limiting protection. If you increase the
CPS-adjustable power level, then the current limit must be retuned so the radio can achieve the
desired power level. If you decrease the CPS-adjustable power level, the current limit can be retuned
to increase protection. You must first determine the test frequency at which maximum transmit
current occurs and then tune on that test frequency.
NOTE: The antenna port should be terminated with a calibrated power meter through a 30 dB RF
pad.

6.4.8Tx Deviation Balance (Compe nsation)
NOTE: This alignment is required after replacing (or servicing) components on the transceiver board.
The Tx Deviation Balance (Compensation) alignment procedure balances the modulation
contributions of the low- and high-frequency portions of a baseband signal. Proper alignment is
critical to the operation of signaling schemes that have very low frequency components (for example,
DPL) and could result in distorted waveforms if improperly adjusted. This procedure needs to be
performed at multiple frequencies to allow for proper alignment across the entire RF band. The RF
band is divided into frequency zones with a calibration point (value) in each zone. When performing
this tuning procedure the PTT Tone Low generates an 80 Hz modulation frequency. The deviation
level of this 80 Hz tone is used as the reference level for adjusting the deviation level of the PTT Tone High, which is a 3 kHz modulation frequency.
This test can be done with either the R-2670 Communication Analyzer or the Agilent 8901
Modulation Analyzer. The method of choice is the R-2670 Analyzer.
• Initial set up using the R-2670 Communication Analyzer:
- Connect a BNC cable between the "DEMOD OUT" port and the "VERT/SINAD DIST/DMM
COUNTER IN" port on the R-2670.
- Press the SPF key on the R-2670 to display the "SPECIAL FUNCTIONS MENU." Move the
cursor to "High Pass," and select 5 Hz on the soft key menu. Select 20 kHz for the "Low
Pass" setting.
- In the "RF Control" section of the R-2670, enter the frequency displayed on the Tuner
screen. Move the cursor to the "B/W" setting and select "WIDE
menu.
- Place the R-2670 cursor in the "Display" zone. Select "AC VOLTS" on the soft key menu.
Move the cursor to the "Range" setting and select "AUTO."
• Initial set up using the 8901 Modulation Analyzer:
- Press the FM MEASUREMENT button. (The "Error 03-input level too low" indication is
normal until an input signal is applied.)
- Simultaneously press the Peak - and Peak + buttons. Both LEDs on the buttons should
light.
- Press the 15 kHz LP filter key.

Chapter 7Encryption
7.1Universal Crypto Module Kits
NOTE: This information applies to both conventional and trunked systems.
The encryption modules use a custom encryption IC and an encryption key variable to perform their
encode/decode functions. The encryption key variable is loaded into the encryption module using a
key variable loader (KVL). The encryption IC corresponds to the particular encryption algorithm
purchased.
Table 7-1 contains the Universal Crypto Module (UCM) kits and their corresponding algorithms for
secure-equipped XTL 5000 radios.
Table 7-1. UCM Kit Listing
Kit NumberDescription

NTN9838DVI-XL ENCRYPTI ON KIT–UCM
NTN9839DVP-XL ENCRYPTION KIT–UCM
7.1.1Secure Interface Boards
Table 7-2 contains the secure interface board kits, which are used in conjunction with the UCM kits.
Every secure-equipped radio must contain one of the two secure interface board kits, which is paired
with one of the UCM kits.
For personalities or talkgroups that are programmed to be secure-selectable, press and release the
Secure button to toggle between Secure and Clear.
• An illuminated secure status annunciator indicates that the transmitted signal will be encrypted
when the PTT button is pressed.
• The absence of the secure status annunciator indicates that the transmitted signal will not be
encrypted.
Page 78
7-2Encryption: Load an Encryption Key
Whether the current personality is strapped for secure or clear, the secure status annunciator
correctly displays the transmit operation as being either secure (encrypted) or clear (non-encrypted).
NOTE: You cannot change from secure to clear while the PTT button is pressed. The radio will
generate an illegal tone and the transmission will be terminated.
Secure-equipped radios automatically determine whether a secure or clear voice message is being
received. This allows you to receive either type of message without having to reset the
programmable secure button.
7.1.3Secure Emergency Operation
Clear or Secure emergency-call operation is determined by the programming of the selected mode
(or talkgroup) or the default emergency mode, if set up. Otherwise, transmit operation is controlled
by the setting of the secure, programmable button. You will not be able to change from Secure to
Clear, or from Clear to Secure, operation during an emergency call.
7.2Load an Encryption Key
7.2.1W3 Control Head
To load an encryption key into a W3 control-head equipped radio:
1. Ensure that an encryption module is installed in the radio.
2. Load an encryption key into the radio’s memory from a key-variable loader (KVL)
using the correct loader for the radio’s encryption type.
To load the key, attach the keyloader cable to the front of the radio. (Refer to the
KVL instruction manual for loading.)
3.
KEYLOADING is displayed on your radio while the key
transfer is in progress.

7.3Advanced Secure Operation
NOTE: The Advanced Secure feature is available only on radios that have been equipped by the
factory to support it. The radio must also be equipped with an encryption module.
Advanced Secure incorporates the Multikey feature and a dual-encryption feature into the existing
secure system. Multikey allows a radio to be equipped with multiple encryption keys. A default key is
included and is associated with the current mode. The keys are strapped to a given mode or are
operator-selectable and can be indexed into groups of keys called keysets. The keys are loaded
using a manual keyloader.
In addition, your radio can support up to eight different encryption algorithms simultaneously.
7.3.1Multikey Operation
The multikey feature can be used in both conventional and trunked applications.
• Conventional Multikey - The encryption keys can be selectively strapped, one per each
channel. In addition, the programmable radio features include operator-selectable keys,
operator-selectable indices, and operator-selectable key erasure. Encryption keys are loaded
into the radio through a KVL.
• Trunked Multikey - If the radio is used for both conventional and trunked applications, the
encryption keys have to be strapped for trunking on a talkgroup, or announcement group, basis.
In addition, a different encryption key can be strapped to other features, such as Private Call,
Dynamic Regrouping, Failsoft, Interconnect, System Wide, or Emergency Talkgroup.
