3.1 Frequency Configuration

Figure 3.3 Frequency Configuration

This radio adopts the 2nd Mixer, the 1st IF 51.65MHz, the 2nd IF 450kHz. The receiver's first local oscillation is generated by the frequency synthesizer. The second local oscillation adopts the 4th harmonic

51.2MHZ of TCXO. The transmitter signals are generated by frequency synthesizer. The reference frequency of frequency synthesizer is generated by TCXO.

3.2 Receiver (RX)

PT5200 SERVICE MANUAL

IF Circuit

The 1st IF signals from the crystal filter are amplified at the first IF amplifier (Q204), and then are sent to the IF processing IC (IC204, TA31136FN). The IF IC consists of the 2nd frequency mixer, the 2nd local oscillator, IF amplifier, limiter, phase frequency detector, and noise amplifier. After amplifying TCXO (X301), the 4th harmonic 51.2MHz is made as the signal source of the 2nd local oscillation. The 2nd oscillation signal（51.2MHz）and the 1st IF signal（51.65MHz）are mixed at IC204 to generate 2nd IF（ 450kHz） . After the 2nd IF signal is amplified and its amplitude is limited at IC204, and then filtered at porcelain filter (wide band CF201/ narrow band CF202， 450kHz), IC204 demodulates and sends out audio signals.

Figure 3.5 IF System

Receiver Audio Signal Processing

IC404， IC405， IC407， and IC408 and their peripheral circuit compose the receiver audio signal processing circuit. IC204 sends audio signals to IC404 for amplification, and then one route goes to IC405 (CTCSS signaling filtering circuit) for waveform shaping and then to IC6-D; one route goes to IC408 where the signals are amplified, de-emphasized, filtered and the HF (high frequency) and LF (low frequency) will be eliminated, and then for the remaining 300-3000Hz audio, one route is sent to volume potentiometer for adjustment and finally sent to the audio amplifier (IC401), and the other one route passes IC407 (2-Tone/5-Tone filter ) to MCU.

Figure 3.4 Receiver (RX)

The Receiver Front Terminal

Signals from the antenna pass through the RX/TX switch (D102, D103, D104); and then undesirable out-of-band signals will be filtered out at the band pass filter (BPF) consisting of C260, L756, L732, C259, C750,C731,D700,C730,L212,C256， C257， D210， C255， L211，C253， and D209; then signals are amplified at the low noise amplifier (LNA) consisting of Q26 and its peripheral components.

The output from the LNA passes the BPF consisting of L207， L206，L720， C248， C702， D207， C245， C244， and C733 for filtering and then is sent to the first grade frequency mixer (Q21).

The First Frequency Mixer

After mixing the receiving signals from LNA with the first local oscillation signals from the frequency synthesizer, the 1st IF signals （ 51.65MHz） are generated. The first IF signals pass the crystal filter (XF203), which will filter the signals of adjacent channel and those out of band.

Figure 3.6 Receiver Audio Signal Processing

Squelch Circuit

Demodulation output from IC204 is sent to the selection frequency noise amplifier, which consists of IC204 inner noise amplifier and C121，R252，R211，C209，and R212 to be filtered off the noise. After being amplified at Q205, noise is sent to D299 for wave checking and then sent to MCU, which determines the noise volume to control the squelch.

Audio Amplifier

IC401 and its peripheral components construct the BTL audio amplifier. Receiving audio signals, voice indication signals, indication tone signals and warning tone signals are collected for audio amplification to drive the speaker. Warning tone has no volume

CTCSS Signal Filtering

The IC204 demodulated output audio signals may contain CTCSS (continuous tone coded squelch system) and DCS (digital coded squelch). The frequency spectrum of CTCSS/DCS is 2-250Hz. The filtering circuit constructed by IC405 can filter out the signals out of the CTCSS/DCS frequency spectrum to ensure MCU to decode CTCSS/DCS more precisely.

3.3 Transmitter (TX)

Transmitter Power Amplifier

Figure 3.7 Power Amplifier and Antenna Switch Diagram

The modulated RF signals from VCO are amplified at Q101, Q102, and Q103 and then are sent to Q104 for amplification. Q104 output power: 4.5W. The Q103 and Q104 gate offset is controlled by APC circuit. Changing gate-offset voltage can control the transmitter output power conveniently.

transmitter output power will decrease. Vice versa, such can ensure steady transmitter output power in different working circumstances. MCU changes the input power to IC3B to set the power.

Transmitter Audio Signal Processing

Figure 3.9 Transmitter Audio Circuit

IC402 and IC408 and their peripherals components construct the transmitter audio processing circuit. After the audio signals from MIC are amplified, one route is sent for demodulation (VOX signals) and then sent to MCU; the other one route passes AGG circuit to IC408, where the amplitude of signals is limited, and signals are filtered and amplified, and then are sent together with CTCSS/DCS to VCO for modulation. J2 is the external MIC socket. When the external MIC is in use, the inner MIC will be cut off automatically, but inner PTT will remain activated.

R167, R168, and R169 are the amplifier current checker; IC101A is the sample amplifier of the amplification current; IC101B is the power comparison amplifier. If the transmitter output power is too large, the amplifier current will increase, IC101A output will mount, IC101B output voltage decrease, the offset voltage added to Q103 and Q104 will decrease, and then the transmitter output power will decrease. Vice versa, such can ensure steady transmitter output power in different working circumstances. MCU changes the input power to IC101B to set the power.

Figure 3.10 Frequency Synthesizer

The radio adopts PLL (Phase Locked Loop) frequency synthesizer. The frequency synthesizer consists of standard oscillator, voltage controlled oscillator (VCO), programmable frequency demultiplier, phase comparator, and low pass filter. Q302， Q307， L304， L310， D304， D302， D310， D308， C309，C310， C308， C307， C322， C323， and C321 constitute VCO. IC30 1 (MB1 5E03S L) i s PL L int egrat ed c ircui t, inc lud ing programmable reference frequency demultiplier, programmable swallowing frequency demultiplier, phase comparator, and charge pump. C326， R316， C328， C327， R317， R318， and R319 construct the low pass filter. The standard frequency is supplied by X301 (TCXO, 13MHz). The standard frequency from TCXO (Temperature Control Transistor Oscillator) are demultiplied by the programmable reference frequency demultiplier at IC301 to acquire 6kHz or

6.5kHz reference frequency (controlled by MCU according to the preset channel frequency). The oscillation frequency from VCO is sent to IC1, and demultiplied by swallowing frequency demultiplier and compared with reference frequency to acquire the error signals. Then pass the low pass filter

PT5200 SERVICE MANUAL

and are sent to VCO to change VCO oscillation frequency to the preset value, and then VCO is locked. N=FVCO/FR N： Frequency demultiplication times FVCO：VCO oscillation frequency FR： Reference frequency

Check Loss of Lock: When PLL is in loss of lock, IC pin14 sends out low level signal to MCU, which controls the transmitter not to transmit and initiate warning tome.

3.5 Voice Indication Circuit

The radio features voice indication, which is very useful at night or in the environment of dim light. MCU stores the voice indication of channels. If Channel Annunciation function has been activated, every time you change the channel, the speaker will sound voice annunciation of the current channel number.

3.6 Power Supply

The radio is equipped with 7.4V, 1200mAh Li-Ion battery. The battery supplies power directly to the transmitter amplifier circuit (Q103, Q104) and the receiver amplifier (IC401). The power supply of other circuits is the regulated 5V power. IC502: 5V low voltage difference, micropower regulator, together with Q10, and Q30 supply big current 5V power to the whole radio. Q502: T5V switch, controlled by MCU. T5V: Supplies power for the front terminal of the transmitter. Q505: R5V switch, controlled by MCU. R5V: Supplies power for the receiver RF amplification, mixing, IF processing, audio signal processing. Q503: C5V switch, controlled by MCU C5V: The 5V power controlled by power saving supplies power for the frequency synthesizer.

Memorizer （E PROM，AT24C64）

Memorizes the radio channel data, CTCSS/DCS data, and other data of function setting and parameter adjustment.

CTCSS/DCS Encoding and Decoding

CTCSS/DCS signals generated by MCU (output form pin20 and pin26, PWM wave) are filtered at the filter circuit and then sent to VCO and TCXO for modulation. CTCSS/DCS signals from the receiver are sent to MCU for demodulation. MCU determines whether the signals contain the same CTCSS/DCS as that set on the radio and decides whether to turn on the speaker.

Power Adjustment

MCU PIN2 sends DC signals to APC to control the transmitter output power.

CTCSS

CTCSS (continuous tone control squelch system) is a squelch control system modulated on carrier wave with continuous subaudio frequency as pilot frequency. If a channel is set with CTCSS, only when both the CTCSS of the receiver and that of the transmitter are identical, communication is available, which avoids interference of other signals.

DCS

DCS (digital code squelch) is a kind of continuous digital code modulated with voice signals on carrier wave to control squelch. 83 groups of standard codes (positive and inverse code) are available. See table 3.2. DCS signals generated by MCU (PWM wave shape) pass the low pass filter to be filtered off the high frequency over 300Hz and then are sent to VCO and TCXO for modulation. VCO modulates the high frequency of DCS signals; TCXO modulates the low frequency of DCS signals. CTCSS/DCS signals from the receiver are sent to MCU for modulation. MCU determines whether the DCS encoding of the receiving signals is identical with that set on the radio and decides whether to turn on the speaker.

Chapter 4 Function Description and Parameter Setting

4.1 Major Functions

4.1.1 16 Channels

The radio stores 16 channels.

4.1.2 Scan Channel (programmable by PC software)

a) Press the key designated as “ Scan” to activate scanning. While in scanning, the radio checks every channel and stops on the channel on which a signal is detected until that signal disappears. If the delay time between signal disappearing and continuing scanning has been preset, the radio will remain on that channel in the delay time even receiving any signals at that time. Only when there are two channels added in the scan list and the scan function has been activated, the radio can start scanning.

4.1.3 CTCSS/DCS

CTCSS/DCS can realize selective calls and group calls. On the same channel, only the two parties whose CTCSS/DCS are identical can communicate. CTCSS/DCS signaling code on the channel is preset.

4.1.4 TOT

The purpose of the time-out timer is to prevent any single person from overlong using a channel to transmit and affecting the whole group communication. If the radio transmits longer than the preset TOT time limit, the radio will stop transmitting and warning tone sounds. To stop the warning tone, release the PTT button. Press the PTT again you can resume transmitting.

TOT Pre-Alert:

You can set the time when the radio generates a "Pre-Alert tone", before the TOT (Time Out Timer) expires. TOT will expire when the selected time passes after a “Pre-Alert Tone”.

TOT Rekey Time:

TOT Rekey-Time sets the "penalty" time in which the radio cannot be re-keyed for transmitting after the Time Out Timer setting is exceeded. During the Rekey time, if you press PTT, warning tone sounds and transmission is prohibited.

TOT Reset Time:

TOT Reset Time sets the minimum "wait" time allowed between transmissions that will reset the Time Out Timer. After setting this, TOT continues even after PTT is released unless the TOT Reset Timer has expired.

4.1.5 Auto Power Save

When no signals are being received or no operations are being conducted for over 10 seconds, the battery power saving will be activated to reduce power consumption. When it is receiving signals or in operating state, battery power saving is inactive. Power Save Type: 1:1, 1:2, 1:4, and OFF.
