CIRCUIT DESCRIPTION
1. Overview
This transceiver is a UHF/FM/P25 portable transceiver
designed to operate in the frequency range of 450 to
520MHz (K, K2, K3) or 380 to 470MHz (K4, K5, K6).
The unit consists of receiver, transmitter, phase-locked
loop (PLL) frequency synthesizer, base band parts, power
supply, and control circuits.
2. Frequency Configuration
The receiver is a double-conversion superheterodyne
using first intermediate frequency (IF) of 49.95MHz and
second IF of 450kHz. Incoming signals from the antenna are
mixed with the local signal from the PLL circuit to produce
the first IF of 49.95MHz.
This is then mixed with the 50.4MHz second local
oscillator output to produce the 450kHz second IF. This
signal is detected to give the demodulated signal in the DSP.
The transmit signal frequency is generated by the PLL
VCO, and modulated by the signal from the DSP. It is then
amplified and fed to the antenna.
The signal is passed through an antenna matching coil,
where the high-frequency components are amplified by a
MOS FET(Q301). The signals are then fed into band-pass
filter that uses varactor diode tuning to reject unwanted
signal components, and is fed to the 1st mixer.
3-2. 1st Mixer
The 1st mixer uses the GaAs IC (IC302). The 1st mixer
mixes the signal with the 1st local oscillator frequency from
the VCO, and converts it to the 1st IF (49.95MHz).
The signal then passes through monolithic crystal filter
(XF300) to remove unnecessary nearby frequency
components. The signal from the MCF is used as the 1st IF
signal.
2nd IF of 450KHz. The 450KHz signal is then passed through
a ceramic filter (CF300) and fed back into IC304 for additional
amplification.

3-4. Wide/ Narrow/ P25 Switching Circuit
Narrow and Wide and P25 settings can be made for each
channel by switching the ceramic filters CF303 (Wide),
CF302 (Narrow), CF301 (P25).
The Wide and Narrow and P25 data is output from pin51
(WN) and pin52 (VN) of CPU (IC5).
When a Wide data (VN : low level, WN : high level) is
received, the 450KHz signal is passed through a ceramic filter
(CF303). When a Narrow data (VN : low level, WN : low level)
is received, the 450KHz signal is passed through a ceramic
filter (CF302). When a P25 data (VN : high level, WN : high
level) is received, the 450KHz signal is passed through a
ceramic filter (CF301).
If the 450kHz signal is a FM signal(Wide, Narrow), the
signal is detected by a ceramic discriminator (CD300). AF
signal is fed to CODEC(IC454), the AF level is adjusted and it
is output from 15pin of IC454. Q304 turns on/off with the
Wide/Narrow data and the IC304 detector output level is
changed to maintain a constant output level during Wide or
Narrow signals.
If the 450kHz signal is an P25 signal, the signal is prepared
by the buffer amplifier (IC308) and fed to FPGA (IC457). The
P25 signal is A/D-converted by the FPGA and DSP (IC8), and
is performed P25 demodulation.
The AF signal is output from 15pin of CODEC (IC454).

CIRCUIT DESCRIPTION
TK-5310
3-5. Audio Amplifier Circuit
• AF signal
The AF signal from CODEC (IC454) is amplified by IC456
and goes through IC458.
The AF signal goes through a DAC (IC462), an AF amplifier
(IC705), and an AF switch (IC701), and is routed to audio
power amplifier (IC702), where the signal is amplified and
output to the internal speaker.
•Audio circuit
CODEC (IC454) extracts the audio signal from the receive
signal in the detection circuit in FM mode. The signal is then
deemphasized and output as a decoded audio signal in P25
mode.
LPF (IC456) removes quantization noise from the audio
signal output of the CODEC.
The switch (IC458) stops the audio signal of the CODEC to
prevent the mixing of BEEP, voice announcement and audio
signal when the BEEP or voice announcement is output from
the CPU. If an optional scrambler board is installed, the audio
path is adjusted so that the audio signal goes through the
scrambler board.
DAC (IC462) controls the voltage amplitude level of the
audio signal according to the volume position of the
transceiver. This determines the volume level output from
the speaker.
The amplifier (IC705) amplifies the audio signal so that the
audio signal level at the final stage amplifier is appropriate.
The volume levels of the 8Ω internal speaker and 16Ω
external speaker are matched using the EXT AFC.
The switch (IC701) adjusts the signal path so that the
audio signal is output to the audio amplifier (IC703) for
external speakers when optional external speakers are
connected. If no external speakers are connected, the audio
signal is output to the audio amplifier (IC702) for the internal
speaker.
IC702 and IC703 output is BTL (Bridge Tied Load).
• AF control
Speaker switching is performed by the CPU (IC5) using
INT AFC or EXT AFC. First, the logic level at the speakers
switching terminal (SSW) on the universal connector is fed to
the CPU. The CPU then outputs data based on this input.
When there is no SP-MIC installed, this logic level
becomes high. When the INT AFC is high, the EXT AFC goes
low, so the AF signal is only fed to the amplifier for the
internal speaker (INT SP) of IC702.
However, when a SP-MIC has been connected, this logic
level becomes low, so the INT AFC goes low and the EXT
AFC goes high. In this case, the AF signal is fed only to
amplifier for the external speaker (EXT SP) of IC703.
3-6. Squelch Circuit
It amplifies the demodulated noise signal from FM IC
(IC304) after filtering through BPF circuit. Then, the amplified
signal is converted to DC signal by the detection circuit. The
converted signal is fed to the CPU (IC5).

4. Transmitter System
4-1. Audio Band Circuit
The audio band circuit of the transmitter system consists
of the following:
• Microphone (Main)
•Microphone (Sub)
• N/C amplifier (Noise canceling mic amplifier) (IC705)
• Switch (Int/ext) (Q455)
• Switch (Mic mute) (Q452)
• AGC (IC452, D450, D451)
• Switch (Scrambler board) (Q454)
• Switch (VGS-1) (IC450)
This transceiver has two types of microphones: main and
sub. The main microphone is located at the front of the
cabinet and the sub microphone is located at the rear of the
cabinet. The audio signal input from these microphones is
synthesized by the N/C amplifier (IC705). The audio signal
from the main microphone is synthesized in normal phase
and the audio signal from the sub microphone is synthesized
in opposite phase. So if the same audio signal is applied in the
same phase to the main and sub microphones, it is cancelled
by the N/C amplifier. If audio signal is input to only the main or
sub microphone, it is not cancelled, but output from the N/C
amplifier.
This prevents ambient noise from entering the audio band
circuit at the next or subsequent stages.
When an optional external speaker microphone is
installed, the Int/ext switch (Q455) cuts off the audio signal
from the main and sub microphones and sends only the audio
signal from the external microphone to the next stage.
The microphone mute switch (Q452) cuts off audio
signals from the main, sub and external microphones.
AGC (IC452, D450, D451) is an amplifier that reduces gain
automatically by greatly increasing the attenuation when the
audio signal of a certain level or higher is present. It controls
the gain so that the audio signal input to the CODEC (IC454)
is not clipped.

CIRCUIT DESCRIPTION
If an optional scrambler board is installed, the switch
(Q454) adjusts the signal path so that the audio signal is input
to the CODEC through the scrambler board.
If the optional VGS-1 (Voice Guide & Storage unit) is
installed, the switch (IC450) will adjust the signal path so that
the audio signal from the microphone is output to the VGS-1
and the audio signal from the VGS-1 is input th the CODEC.
The audio signal is input to the CODEC (base band circuit)
through the above path.
4-2. Base Band Circuit
The base band circuit of the transmitter system consists
of the following:
• CODEC (IC454)
• DSP (IC8)
• LPF (IC456)
• Buffer (IC459)
• DAC (IC462)
•Amplifier (IC463)
The audio signal output from the base band circuit is
converted to digital data of a sampling frequency of 48 kHz
and a quantization resolution of 16 bits by the CODEC
(IC454). This digital data is sent to the DSP (IC8), and voice
signals of 300 Hz or lower and frequencies of 3 kHz or higher
are cut off and an audio range 300 Hz to 3 kHz is extracted.
The audio signal is then pre-emphasized in FM mode and
synthesized with the signals, such as QT and DQT, as
required, and is then output from the CODEC. In P25 mode,
the audio signal is converted to the C4FM base band signal
and output from the CODEC. The DTMF and MSK base band
signals are also generated by the DSP and output by the
CODEC.
LPF (IC456) removes quantization noise from the base
band signal output from the CODEC.
The buffer (IC459) sets the base band signal level to the
DAC input range.
The DAC (IC462) assigns the base band signal to the VCO
(Q107) and VCXO (X100).
At this time, the level output according to the transmit
carrier is fine-adjusted according to the modulation method
of FM Wide, FM Narrow and P25.
4-3. Transmit Signal Amplification Circuit
(From T/R switch to Final amplifier)
The transmit signal passing through the T/R switch
(D200) is amplified to approx. 50 mW by the two transistor
amplification circuits (Q200, Q210). The transmit signal
output from Q210 passes through an attenuator to improve
high-frequency signal matching is amplified by the drive
amplifier (Q202) and applied to the final amplifier (Q205). The
signal applied to the final amplifier is amplified by the final
amplifier so that the antenna output is 4 W (1 W for Low
Power).
4-4. High-Frequency Signal Switch Circuit
(From Antenna switch to ANT output)
The transmit signal output from the final amplifier (Q205)
passes through the antenna switch (D202, D203) and LPF,
and goes into the SPDT switch (IC202, IC203) which changes
the antenna connector (CN204) and the universal connector
(CN205).
The transmit signal passing through the output change
switch passes through the surge protection HPF and
spurious removing LPF and then goes to the antenna
connector (CN204) or the universal connector (CN205),
specified by the SPDT switch (IC202, IC203).
4-5. APC Circuit
The APC circuit detects the current of the drive amplifier
(Q202) and final amplifier (Q204) during transmission and
controls the output power by controlling the current.
It detects the current using R220 and R222 and applies a
drop voltage between both resistors during transmission to
APC (IC201). It controls the transmission current of the drive
amplifier and final amplifier so that it is constant by
comparing this current with the reference voltage output
from pin 7 of IC200. The reference voltage input to pin 5 of
IC200 is output from the DAC (IC462). High/Low power
output is set according to the DAC output voltage.

5. PLL Frequency Synthesizer
The PLL Frequency Synthesizer consists of the following
components:
• VCXO (X100)
• VCO (Q106, Q107)
• Doubler (Q110, Q111)
• PLL IC (IC101)
• Local switch (D200, D308)
5-1. VCXO (X100)
VCXO (X100) generates a reference frequency of 16.8
MHz for the PLL frequency synthesizer. This reference
frequency is applied to pin 8 of the PLL IC (IC101).
The VCXO oscillation frequency is fine-adjusted by
controlling the voltage applied to pin 1 of the VCXO with DAC
(IC462). It is also controlled with pin 1 of the VCXO if the
output from VCXO is modulated.
5-2. VCO
There is a RX VCO and a TX VCO.
The TX VCO (Q107) generates a transmit carrier and the
RX VCO (Q106) generates a 1st local receive signal.
The VCO oscillation frequency is determined by one
system of operation switching terminal "T/R" and two
systems of voltage control terminals "C/V" and "V-assist".
The operation switching terminal, "T/R", is controlled by the
control line (T/R) output from the CPU (IC5). When the T/R
logic is low, the VCO (Q107) outputs the transmit carrier and
when it is high, VCO (Q106) outputs a 1st local receive signal.
The voltage control terminals, "CV" and "V-assist", are
controlled by the PLL IC (IC101) and CPU (IC5) and the output
frequency changes continuously according to the applied
voltage. “V-assist” is controlled directly by a microcomputer
to change the VCO oscillation frequency at high speed.
However, its accuracy is low and the VCO frequency cannot
be matched accurately with the desired transmit carrier or
the 1st local receive signal. “CV” is controlled by the PLL and
is used to accurately match (look) the desired frequency of
the VCO oscillation frequency. For the modulation input
terminal, "MOD", the output frequency changes according to
the applied voltage. This is used to modulate the VCO output.
"MOD" works only when "T/R" is low.
5-3. Doubler (Q110, Q111)
The doubler (Q110, Q111) extracts the twice harmonic
component from the signal output from the VCO. This twice
harmonic component is then fed into pin 5 of the PLL IC.
5-4. PLL IC (IC101)
PLL IC compares the differences in phases of the VCO
oscillation frequency and the VCXO reference frequency,
returns the difference to the VCO CV terminal and realizes
the "Phase Locked Loop" for the return control. This allows
the VCO oscillation frequency to accurately match (lock) the
desired frequency.
When the frequency is controlled by the PLL, the
frequency convergence time increases as the frequency
difference increases when the set frequency is changed. To
supplement this, the CPU is used before control by the PLL
IC to bring the VCO oscillation frequency close to the desired
frequency. As a result, the VCO CV voltage does not change
and is always stable at approx. 2.5 V.
The desired frequency is set for the PLL IC by the CPU
(IC5) through the 3-line "LE", "DAT", "CLK" serial bus. Whether
the PLL IC is locked or not is monitored by the CPU through
the “UL” signal line. If the VCO is not the desired frequency
(unlock), the "UL" logic is low.
5-5. Local Switch (D200, D308)
The connection destination of the signal output from the
VCO is changed with the diode switch (D200) that is
controlled by the transmission power supply, 5T, and the
diode switch (D308) that is controlled by the receive power
supply, 5R.
If the 5T logic is high, it is connected to a send-side prepre-drive (Q200). If the 5T logic is low, it is connected to a
receive-side mixer (IC302).

signal input.
2) Reading system, zone, frequency, and program data from
the memory circuit.

stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily
written from an external devices.
The EEPROM (IC3) stores the last channel data, the scan
on status, and other parameters.
■ Flash memory
Note : The flash memory stores the data that is written by
the FPU (KPG-95D), and firmware program (User mode, Test
mode, Tuning mode, etc.). This data must be rewritten when
replacing the flash memory.
■ EEPROM
Note : The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.
■ Real-time clock
The clock function is based on real-time clock IC (IC2).
When the power supply is off, it is backed up by an internal
secondary lithium battery

6-2. LCD (K2, K3, K5 and K6 models only)
The LCD is controlled using the bus lines on the connector
(CN800) of the control unit (X57 B/5).
The LCD contrast voltage is corrected using IC800. The
thermometry result used by the temperature IC (IC1) is
corrected by the CPU (IC5), and the contrast voltage is output
as a pulse ripple from the LCDV terminal (pin 28) of the CPU.
The filter then smoothens the voltage which in turn is input
into pin 3 of IC800.
6-3. Temperature Detection Circuit
The temperature detection circuit detects the
temperature using a temperature IC (IC1) and corrects the
thermal characteristic change of the squelch or LCD.
6-4. Key Detection Circuit
Keys are detected using three shift registers (IC801,
IC802, IC803).
The KIN signal that is normally pulled down goes high
when any key is pressed.
6-5. Low Battery Warning
The battery voltage is divided using R22 and R23 and is
detected by the CPU (IC5). When the battery voltage falls
below the voltage set by the Low battery warning
adjustment, the red LED blinks to notify the operator that it is
time to replace the battery. If the battery voltage falls even
more (approx. 5.8V), a beep sounds and transmission stops.

6-6. Battery Type Detection
The transceiver automatically detects the battery type,
measuring the resistance between the S-terminal and GND
terminal on the battery pack and changes the supplied
voltage to the S-terminal as below. The microprocessor then
detects the battery type.

6-7. VOX
The VOX function can be used only with an external
microphone.
The VOX (Voice Operated Transmission) function detects
voice input to the microphone and automatically switches
between transmission and reception. However, if a
scrambler board is installed (Extended Function Voice
Scrambler is selected with FPU), VOX does not operate.
CIRCUIT DESCRIPTION
TK-5310
If the microphone input exceeds a certain level,
transmission automatically begins. If the input falls below a
certain level, the transceiver automatically returns to receive
mode.
The transceiver realizes this function using DSP (IC8).
6-8. DSP
The DSP circuit consists of a DSP (IC8), a CODEC (IC454)
and processes the base band signal. The DSP operates on an
external clock of 9.216MHz (the same as the CPU), the I/O
section operates at 3.3V and the core section operates at
1.5V. The DSP carries out the following processes:
• C4FM encoding
• Analog FM pre-emphasis/de-emphasis
• Vocoder (IMBE) processing between audio codec and
modulation/demodulation
• CAI processing, such as error correction encoding
• QT/DQT encoding/decoding
• DTMF encoding/decoding
• MSK encoding/decoding
• 2-tone encoding/decoding
• Compressor/expander processing
• Transmit/receive audio filtering processing
• VOX processing
•Microphone amplifier AGC processing
• Audio mute processing
•Modulation level processing
6-9. FPGA
The FPGA(IC457) I/O section operates at 3.3V. and the core
section operates at 2.5V. The FPGA has the following function.
• Demodulation (C4FM,CQPSK)
• Shift register(8CH)
• Level convert Buffer amplifier(5V➝3.3V)(9CH)
• Generates 1.536MHz for the demodulation and CODEC.
7. Power Supply Circuit
The power supply voltage (+B) is supplied from the
battery terminal of the TX-RX unit (X57 A/5) and is then
passed through the fuse (F600).
If +B voltage is detected by the voltage detection IC
(IC706) and it is above 5.6V, then the 3V regulator (IC704) CE
pin becomes high and the 3.0V power source turns ON.
Additionally, when the VOL SW is ON, the 3.6V DC/DC
converter (IC710) CE pin becomes high and the 3.6V power
source turns ON.
The output from the 3.6V DC/DC converter (IC710)
provides the power source for three regulators (IC707,
IC708, IC711) and the 1.5V DC/DC converter (IC709).
The voltage output from the 1.5V DC/DC converter
(IC709) is detected by the 33A SW (Q712).
When the CE pin of the 3.3V regulator (IC708) is high, the
33A power source turns on.
When the 3.6V power source turns on, the 5V regulator
(IC712) CE pin becomes high and 5M is supplied with the
power source.
The three regulators (IC707, IC708, IC711) and the DC/DC
converter (IC709) start the CPU, DSP, FPGA, etc. After the
CPU starts up, it begins controlling two regulators (IC601,
IC600) with the 5CC and PWR signals.
When the Power SW (Q602) is turned on with the PWR
signal, the 15V DC/DC converter (IC713) starts up. IC712,
IC601, and IC600 is supplied from +B.
The output from IC600 is switched between 5R (which is
turned on while receiving) and 5T (which is turned on while
transmitting), and is controlled by the CPU.
The output from of the 5V regulator (IC610) is controlled by
Q604 and is used as a power source for 5MCS, for an optional
accessory which is connected to the universal connector.

8. Signaling Circuit
8-1. Encode (QT/DQT/DTMF/2-tone/MSK)
Each signaling data signal of QT, DQT, DTMF, 2-tone and
MSK is generated by the DSP circuit, superposed on a modulation signal and output from pin 16 of the CODEC (IC406).
The modulation balance of the QT/DQT signal is adjusted
by the D/A converter(IC411) and the resulting signal is routed
to the modulation input of the VCO and VCXO (X301).
The each deviation of the TX QT, DQT, DTMF, 2-tone and
MSK tone is adjusted by changing the output level of the
CODEC and the resulting signal is routed to VCO and VCXO.
The RX DTMF tone is output from pin 15 of the CODEC,
passes through the receive audio signal system, and is output from the speaker.
8-2. Decode (QT/DQT/DTMF/2-tone/MSK)
The audio signal is removed from the FM detection signal
sent to the DSP circuit and the resulting signal is decoded.
9. Compander Circuit
The term “compander” means compressor and expander.
The compander reduces noise by utilizing a compressor and
an expander.
The transceiver contains DSP(IC8) to perform this operation. The transceiver compander can be turned on or off using
the FPU.
