3.1.1. Tx Circuit
Figure 3-2 Tx Circ uit Dia g r am
Tx circuit mainly includes four parts below:
• RF Power Amplifier Circuit
The carrier signal generated by VCO will be modulated and preliminarily amplified before entering Tx
circuit. The signal will first pass through a Π-type pure resistance attenuator R536 R537 R538 to realize
the level isolation between the power amplifier circuit and Tx VCO. Then the modulation signal enters the
firs t pre-drive amplifier (Q504) for preliminary amplification, which generates a certain isolation between
the first and second amplifier; The amplified signal will then enter the next pre- drive am plifi er (Q5 03 and
drive amplifier (Q502 RD01)) for further power amplification so as to ensure that enough drive power

signal can be offered to the last power amplifier (Q501 RD07) for final power amplification. After being
processed by a set of ampli f iers at several levels, the Tx si gnal will complete the output im pedance match
through a microstrip line at the output terminal of the last power amplifier, through which the output power
loss caused by impedance mismatch can be av oi ded. The Tx signal will then pass the Rx/Tx switcher and
enter the LPF.
• Low Pass Filter Circuit for Harmonic Suppression
Low pass filter which suppresses harmonic wave is a high level low pass filter consisting of capacitor and
inductor with concentrated parameters. The out-of-band harmonic wave and spurious signal can be
further suppressed on the condition that the certain in-band fluctuation is satisfied throu gh this filter.
• Auto Power Control Circuit ( APC)
The drain current from the drive power amplifier and end-level power amplifier passes the sampling
resistors (R559 R560 R561) and the subtraction circuit which consists of the first operational amplifier to
realize the transformation from current to voltage. The voltage will be compared with the PAC control
voltage value output from DAC (U3 01 pin 29) at the secon d operat iona l ampli fier, and the output deviat io n
voltage will change the Tx power strength by controlling the grid bias voltage of power amplifier
tube(including drive lev el and end level).
• Audio Processing
The microphone converts the speech signal to speech electric signal, and the signal will be amplified by
U103 before being input in to ADC of codec ( U201 HR_C5000) for sampling, it will then be output into DSP
after audio being digitally processed, and sent to DAC for modulation signal conversion, the modulation
signal will be separate d into path I and Q for modulat ing V CO , TCXO.
3.1.2. Rx Circuit
Figure 3-3 Rx Circuit Diagram
Rx circuit mainly includes:
RF band-pass filter, low noise amplifier, frequency mixer, IF filter, IF amplifier, IF processor and audio
circuit.
Page 4 of 61
Page 7
TP620 Service Manual
• Rx Circuit RF Part
The high frequency signal from low-pass filter passes the front stage electrically tunable band-pass filter
controlled by electric lev el and outp ut by DA C (U301 PIN29) so as to filter out the out-of-band i nterfer en ce
signal, sending ef fec tive b and-p ass signa l into the low noise amplifier (Q505) . The amplified signa l p ass es
again the band-pass filter controlled by electric level and output by DAC so as to filter out the out-of-band
interference signal caused by amplification, sending effective high frequency signal into freque ncy mixer
(Q506).
The effective signal passes RF band-pass filter and low noise amplification and enters the frequency
mixer Q506, meanwhile, the first local oscillation generated by VCO passes the low-pass filter and enters
Q506 for making frequency difference with effective signal so as to generate the first IF signal. The signal
passes th e frequenc y selector network which consists of LC; it further suppresses the other carrier waves
other than the first IF, and increases the isolation between the frequency mixer and IF filter. The IF signal
will be filtered by the XF501 crystal filter, and then sent to the first IF amplifier (Q507) f or amplific ation
before being sent to the IC for IF processing (U501, GT3136).
The third harmonic frequency 50.4MHz produced by TCXO(X601 16.8MHz) is amplified by frequency
selector and become the second local oscillation signal source. The second local oscillation (50.4MHz)
mixes with the first IF signal in U501, generat in g t he s econd I F ( 450kHz). The second IF will be amplified,
limiting am plitud e inside U 501, and filter ed by the ceram ic filter CF50 1 450 kHz before going back to U501
for demodulating and outputting the audio signal.
• Rx Circuit Audio Section
A. Digital Channel Audio Access: The seco nd I F signal output from the eleventh pin of U501 is amplified
by Q509 and sent to U201 for ADC sampling and be ing conv ert ed to dig it al sig nal; af ter the digital audio
signal is compressed, decompressed and decoded by U301, U201 will complete DA conversion and
output audio signal from the 10th pin, and the audio signal will be amplified by U203 and sent to the
audio power amplifier IC101.
B. Analog Channel Audio Access: The audio signal output from the 9th p in of U501 is amplified by U102
and its unit circuit. The high frequency and low frequency will be removed from the audio signal,
keeping only the voice compone nt between 300 Hz to3000 Hz . The v oice compone nt will be ad juste d by
volume potentiometer and sent to audio power amplifier IC101.
C. Analog Channel CTCSS/DCS Signaling Access: The audio signal output from the 9th pin of U501
may include CTCSS/DCS signal. The 300Hz low-pass filter circuit composed of U101 filters out the
signals out of the CTCSS/DCS spectru m. After CTCSS/DCS is amplified, it will be sent to the 25th pin of
U301.
D. Analog Channel Squelch Circuit: The modulated output from U501 is sent to the frequency selector
noise amplifier which is compos ed of U501 inter nal noise a mplifier and C555, R525, R524, C554, C553,
R527; the noise will be selected from the modulation signal and detected internally before being
outputting by the 14th pin and transformed as direct electric level to reach MCU U301; MCU identifies
the electric level strength and controls squelch.

3.1.3. Frequency Synthesizer Circuit
Figure 3-4 Frequency Sy nthesizer Circuit Diagram
Frequency synthesizer circuit is composed of VCO and PLL, and it is the kernel module of the whole TRx
system. When transmitting, the circuit supplies accurate carrier frequency; when receiving, it supplies
stable local oscillati on signal. The circuit dire ct ly influences some of the important functions in the system.
• PLL Wor k i ng Principle
The 16.8MHz frequency generated by the reference crystal oscillator enters the frequency divider of PLL
chip, and becomes reference fre que ncy (i.e. step freque ncy f1). The frequency generat ed by VCO passes
LPF for filtering out the second harmonic wave and enters PLL chip for frequency division and gets
frequency f2. The frequency f2 compares with f1 on phase difference in phase comparator, producing
continuous pulse current. When the pulse current passes the loop filter, it starts to accumulate RC and
converts to CV voltage. The CV voltage is sent to the VCO varactor, directly controlling and adjusting the
VCO output frequency until CV becomes constant. PLL will be currently locked, and the stable frequency
output from VCO pass es t wo buffer amplifiers befor e ent er ing the TRx access.
• The Working Principle of Voltage Controlled Oscillator
The voltage controlled oscillator applies oscillation mode of three point capacitor. It changes the control
voltage of varactor to get different output frequency. Rx VCO is composed of oscillator circuit and Q603.
Tx VCO is composed of osci llat or c ircuit and Q601, supplying carrier w ave of TX signal.

Figure 3-5 Power Structure Diagram
This radio applies 7.4V, 2000mAh lithium battery, RF power amplification (Q501, Q502), AF power
amplification (IC101), and direct battery power supply.
The power circuit is composed of power-on/off circuit, 5C, 5R, 5T, and 3.3V DC-DC volta ge stabilizing
circuit.
Power-on Circuit: When SW 401 is closed, the B level of Q402 becomes high electrical level, and the
switch tube Q401 becomes conductive. The power supplies electricity for every power module through
Q401, when MCU is powered on, POW_HOLD will output high electric level to keep Q401 constantly
conductive so as to turn on t he r adio.
Power-off Circuit: When SW401 is cut off, POW_DET test pin becomes low electric level, and
POW_HOLD pin of MCU will first st ays on high e lectric level for a w hile before out putting low elect ric level .
The Q402 B level thus becomes low electric level, cutting off the switch tube Q401 and the power to turn
off the radio.
5C voltage stabilizing circuit: U404 applies 5V LDO voltage stabilizer and supply 5v power for PLL circuit.
Meanwhile, the 67th pin of U301 outputs high and low electric level to control the enable pin of U404,
making the voltage stabilizer switches between 5V and 0V so as to realize the functions such as energy
saving and Tx/Rx switch.
5R voltage stabilizing circuit: U403 applies 5V LDO volt age sta bilizer, and sup plies 5V power for Rx circ uit.
Meanwhile, the 66th pin of U301 outputs high and low electric level to control the enable pin of U403,
making the voltage stabilizer switches between 5V and 0V so as to realize the functions such as energy
saving and Tx/Rx switch.
5T volt age st abil izing c ircuit : U402 applies 5V LDO voltage st abiliz er, and supplies 5V pow er for Tx c ircuit.
Meanwhile, the 34th pin of U301 outputs high and low electric level to control the enable pin of U402,
