Chapter 3. Circuit Description
3.1 RF Circuit
Figure 0-1 RF schematic

TM840 Service Manual
3.1.1 Transmitter Circuit
Figure 3-2 Transmitter Circuit Schematic
Transmitter circuit is composed of the following three parts:
RF Power Amplifier Circuit
The TX VCO generates a carrier signal, then it will be modulated and amplified before it goes into transmitter circuit. The
signal will pass through a Π type attenuator, and it is a process which allows the interstage isolation between the RF power
amplifier circuit and the TX VCO. The signal enters a pre-driver amplifier(U42) for the first amplification. Then the signal will
go to next driver amplifier(U51) to obtain further amplification, which will provide adequate power for the final stage amplifier
module(U100) to finish the final power amplification. After multi-stage amplification, the transmitter signal will pass through
the TX/RX switch, then enter the Low Pass Filter.
Low Pass Filter Circuit
The low pass filter is a high order low pass filter which can suppress harmonics. The filter is composed of lumped parameter
inductors and capacitors. Via this filter, the capability of attenuating, the spurious signal and harmonics can be increased
when the in-band ripple conditions are satisfied.
Auto Power Control Circuit( APC ,including the temperature detection and VSWR stationary wave detection
circuit )
When radio is transmitting, the power orientation coupler will detect forward and reverse output power, which will pass
through wave detecting diode for wave detecting and sampling. The sampled RF signal will pass through an attenuator, to
the PA power controller. The output voltage will be compared(IC1-A) firstly, the compared voltage will be compared again
with the pre-set voltage(IC3-A), the output voltage will be sent to PA power controller(IC2), then compared with the APC
reference voltage and sample signal for another comparison. The voltage will be output by the power controller and the
controller will adjust the grid voltage in the RF module to achieve VSWR stationary wave detecting and power control. In the
meantime, it will judge the VSWR base one the voltage and software pre-set conditions, and protect the power amplification
circuit by controlling theAPC voltage. The APC voltage output by DAC will pass through a temperature-compensation circuit,
which allows compensating the power fluctuation that is caused by temperature difference. Then the temperature
protection circuit will amplify the voltage division network which is composed of thermistors, after an A/D conversion, it will be
4

TM840 Service Manual
provided to OMAP. OMAP will combine the VSWR rate to define the APC value to achieve the thermal protection.
3.1.2 Receiver Circuit
Figure 0-2 Receiver Circuit Schematic
The receiver circuit includes RF band pass filter, low-noise amplifier, mixer, IF filter, IF amplifier and IF processor.
The signal received from the antenna will pass the front end LPF and Tx-Rx switch controller, then it will enter the RF
electronic tuning band pass filter for frequency selecting.After that, it will be amplified by the low noise amplifier, then sent to
mix up with local oscillator signal which is provided by the first stage mixer IC3003 and VCO to achieve frequency conversion.
The first IF signal(UHF:73.35MHz,VHF:51.65MHz) output by the mixer will pass the IF filter to achieve channel selection.
Then it goes to Q18/19 for IF amplification, after that, the signal will be sent toAD9864 for second mix up andADC sampling.
After the processing, the unmodulated I/Q digital signal will be output to DSP for FM/4FSK modulation, and after voice data
uncompressing, the signal will be sent into the audio codec chip for D/A conversion. Finally, the signal passes the audio
amplifier to speaker, then sent out.
The IF signal (UHF:73.35MHz,VHF:51.65MHz)output by IF amplifier will enter the AD9864 via pin 47 of U4000 for second
frequency mix up andADC sampling, then output the unmodulated I/Q digital signal to DSP for FM/4FSK modulation.Please
refer to figure 3-4.
The reference frequency of AD9864 is 19.2MHz. The second local oscillator VCO is composed of external oscillator tube,
varactor and some other components. The local oscillator VCO provides a local oscillator signal(UHF:71.1MHZ,VHF:
49.4MHz).And the external LC syntony circuit generates aAD9864 clock frequency, which is 18MHz.

3.1.3 Frequency Generation Unit(FGU)
Figure 3.5 Frequency Generation Unit Diagram
Frequency generation unit(FGU) is composed of VCO and PLL. It is the core module of the TX-RX system. When
transmitting, it provides accurate carrier frequency, while receiving, it provides stable local oscillator signal. It has direct
influence on system performance.
(1)Working Principle of PLL
Benchmark crystal generates a 12.8MHz frequency, then it goes into frequency divider of the PLL chip to create a reference
6

TM840 Service Manual
frequency(i.e step frequency f1). The frequency generated by VCO will be harmonics suppress processed twice. Then it
enters the frequency divider of the PLL chip to create frequency f2. F2 will be compared with f1 in phase detector (PD) ,
which will generate a continuous pulse current. When the pulse current passes through the loop filter for RC integration, then
it is converted to CV voltage. The CV voltage will be sent to the varactor of VCO to adjusts and control the output frequency,
till the CV becomes constant. Then the PLL will be locked, the stable frequency output by VCO will go to the TX-RX channel
before passing through two buffet amplifiers.
(2)Working Principle of VCO
VCO employs oscillation mode three point capacitance. It can change the control voltage(i.e CV voltage) of varactor to
obtain different output frequencies. Rx VCO, which provides local oscillator signal, is composed by oscillation circuit and
Q24/Q29, while TX VCO is composed of oscillation circuit and Q27/Q28, and it provides transmitting signal carrier.
Two- Point Modulation
To obtain better modulation accuracy and 4FSK bit error rate when transmitting, two-point modulation is employed. MOD1
and MOD2 send the modulated signal to PLL reference crystal oscillator and VCO modulation end respectively., and to
modulate Tx benchmark crystal oscillator and VCO respectively.
3.1.4 GPS Circuit
Figure 3.6 GPS Circuit Diagram
The radio positioning is achieved by GPS module. This module integrated a baseband processor, a LNA and a SAW. The
GPS signal, whose frequency is 1575.42MHz, is received from the antenna inductor, then passes HPF to filter the Tx/Rx
in-band signal. After a frequency selecting process, the GPS signal will enter GPS module for amplification and filter, then
will be sent to baseband for related calculating. The calculated GPS positioning information will be sent to OMAP for
processing via UART port. In the meantime, U4 can send related command information to GPS module via UART port.
Finally, the processed data information will be delivered to LCD for display by U4.

3.2.3 Audio processing
Figure 3.8Audio Processing Diagrams
Audio module is made for audio output and input. This system employs U17 as the audio codec, which is to proceed the
analog and digital signal converting. Power amplifier U18 is used to amplify the analog signal and drive power.
DSP processes the digital audio signal(audio encoding/decoding etc), while the IF processor U4000 will convert and process
the RF IF frequency signal, and send the I/Q signal to DSP for further processing, then DAC U103 will processes the
digital-analog converting.
(1) Audio singal Flow
The microphone converts the audio signal to electrical signal, which will be amplified by PGA of codec, then sent to ADC of
codec for sampling. The signal will be sent to DSP processing after digital audio processing, then will be sent to DAC(U105)
to convert to modulation signal. The modulation signal will be modulated again and amplified in the RF module before finally
sent out by antenna. This radio has two MIC signal, which are internal MIC and external MIC. The internal MIC signal comes
from handheld speaker, while the external MIC signal is from 26PIN of second development interface. Also the internal MIC
signal is divided into two parts, and one will be sent to codec U17 for analog-digital converting,and the other one will be
sent to 26PIN second development interface for second development after processed by auxiliary audio circuit.
The RF signal received from RF module will be sent to DSP after converting by IF processor U4000. Then it will be
demodulated and processed by DSP, then sent to codec digital audio processing module for digital audio processing. And
then the signal is sent to DAC of codec to convert to analog audio signal. Codec U17 has five analog audio signal output
ends. Two of them will be sent to audio amplifier(U18) for amplification as the drive signal for internal and external speaker.
Then the other two will be sent to 26PIN second development interface. The other one is for the MIC input signal for optional
