TR850 Service Manual

Transmitter circuit includes three parts:

 Two Point Modulation Circuit

The RF center frequency cal ibrat ion from the baseband and the low frequency part of 4FSK signal will be processed with addition algor it hm, then sent to the DAC to get MODE1 signal. The MODE1 directly enters the reference cloc k X100, which is used for cent er frequenc y control a nd low fre quency modulation.

The MODE2 signal, which passes the two-level low pass filter which is composed of IC301s for DAC sampling interference filter , will be sent into VCO for high frequency part modulation.

 Transmitter Frequency Generation Unit Circuit

The transmitter PLL includes two VCOs,one PLL(IC100) IC SKY72310 and reference clock X100. The transmitting frequencies of the two VCOs controlled by the TXVCOSELECT signal are 400~435M Hz a nd 435~470MHz respectively.(VHF is 136~ 155MHz and 155~174MHz)

a. Working Principle of Voltage Controlled Oscillator The Tx Module employs two VCOs which cover the band of 400~435MHz and 435~470MHz (VHF is

136~155MHz and 155~174MHz). The switch of VCO is controlled by the TXVCOSELECT signal. VCO employs thr ee point capac itanc e oscillation circuit. The VCO that c overs the band of 40 0~435M Hz (VHF is 136~155MHz) is composed of D106~D109、L119、Q106 and some other components, while the VCO covers the band of 435~470MHz (VHF is 155~174MHz) is composed of D101~D104、L107、Q105 and some other components .

The 12.8 MHz reference clock (X100) output signal which is controlled by MODE1 signal will enter the reference input port of PLL IC (IC100 SKY72310), then according to the configuration of register, it will be divided to get 3.2MHz reference frequency, and the frequency will be compared in phase difference with the signal generated by t he frequenc y div ision which is resulted from the VCO’s enter into the input port of PLL chip. The PLL (IC100 SKY72310) PD pin will output the positive or negative pulse current which is in

current passes the loop f ilter, it will be converted to CV voltage via RC integral. The the CV voltage will be sent to the VCO varactor to adjust and control the output frequency from the VCO until the CV voltage becomes constant. The loop is locked in the meantime.

 Buffer Amplifier Circuit

VCO outputs the modulated carrier signal to enter Q2002 for buffer amplication and then passes the LPF U402 to eliminate the harmonic wave. A fter that, the signal will go into IC306 for pre-amplification, then passes the LPF to filter the harmonic wave again, and the signal is output to the SMA connector which is connected to the transmitt ing power amplification.

3.1.2. RF Power Amplifier Module Circuit

Figure 3-2 RF power amp lification module

The power amplifier module will amplify the modulated carrier signal from the transmitter module to a certain power level, t hen send to the transmitter port.

The power amplifier modu le includes the three parts:

 Power Amplification Part

The modulated carrier from the transmitter module will enter Q102 for pre-amplification, then the signal will attenuate to a certain level to make the amplitude of the signal which will be input with U100 operates between 17~20dBm. Under the control of POWERCONTROL signal, the RF signal output from U100 will pass the LPF to suppress the harmonic wave and collect power stationary wave sample from the directional coupler before being sent to the antenna port.

 APC and Stat ion ar y Wave Protection Circuit

The directional coupler detects the forward and reverse directions RF signal and passes the Q103,Q104 to convert the signal to the DC voltage which is corresponding to the forwardand reverse direction power. After the voltage division, the forward direction DC voltage with the reverse direction voltage pass the selection switch which is composed of D201,D202 and enter IC100(NJM2904) for buffer amplification before being sent to the reverse phase input port of the operational amplifier of IC100(NJM2904).

POWERCONTROL control signal form the baseband will be sent to the identical phase input port of IC100(NJM2904)’s operational amplifier. After the operational amplification and external circuit’s function calculation, the signal is output as a conrol signal which controls the U100 gain control port to ensure that the actual output power remains stable when the impedance matches and to decrease the output power for power amplifier protection when the impedanc e mismatches.

 Temperature Detection Circuit

The continuous temperature rise can lead to a decrease of transmitting power. The temperature detection employs IC101(DS18B20) to collect the digital temperature sample.W hen the temperature exceeds the threshold value, the fan wi ll be switched on for heat dissipation.

3.1.3. Rx Module Circuit

Figure 3-3 Receiver Module

 Receiver Circu it

The receiver circuit includes RF Band pass filter, Low-noise amplifier, mixer, IF filter, IF ampli fier and IF processor.

The signal from the receiving port first passes the low pass filter to suppress the high frequency interference, and passes the electrical tuning BPF to suppress the image interference and the out-band interference.The in-band signal is sent to the low noise amplifier (IC3000) and the amplified signal passes the electrical tuning BPF contr olled by BPFADJUST to filter t he out-ba nd interf erence, so the ef fect ive high frequency will be sent to the mixer(IC3005). Meanwhil e, the first loc al oscillation passes the LPF and gets mixed with the effective signal in IC3005 to generate the first IF signal (51.65MHz). The first IF signal passes the crystal filter (Z3001) to suppress the out-band signal. The signal is then sen t to IF amplif ier (IC6003) for amplification before being sent to the crystal filter to strenghthen the suppression of the the adjacent channel. After being sent to the limiting amplifier composed of Q3001 and Q3002, the signal enters AD9864 (U4000) for the second freq uency mixing ,IF amplification and AD sampli ng. The digital IQ signal will be finally output to the baseband for further processing.

Page 11

 IF Processor Circuit

Figure 3-4 IF Processor

TR850 Service Manual

The 51.65MHz IF signal output from the IF amplifier enters the AD9864 via its pin 47, and it finishes the second frequency mixing in the AD9864 to convert the fisrt IF to the second IF. The second IF signal is converted to the digital signal through the ADC sampling and output from the SSI port, and the digital signal is sent to FPGA f or demodulation.

The reference frequency of AD9864 is 12.8MHz. The second local oscillation VCO is composed of external oscillation tube, varactor, and related components. The VCO provides the 49.4MHz local oscillation signal. The clock frequency of AD9864 is18MHz and it is generated by external LC resonance circuit.

 Rx Module Frequency Generation Unit C irc uit

The Rx Module Frequency Generation Unit Circuit is composed of two VCOs and one PLL. Two VCOs cover the band of 400~435M Hz and 435~470MHz respectively (VHF is 136~155MHz and 155~174MHz).

a. Working Principle of PLL The 12.8MHz clock frequency provided by the baseband will enter the frequency divider for division, and

then the 3.2MHz phase detecting frequency will be generated. The signal generated by VCO enters the PLL chip for frequency division, and goes into the PD to get compared in phase difference with the signal generated by frequency division of reference clock, thus the continuous pulse current is generated. The continuous pulse current p asses t he loop filter and w ill be conv erted t o CV volt age via R C integral. The C V voltage will be sent to the varactor, and it controls and adjusts the VCO output frequency until the CV becomes constant. In the mean time, the PLL is locked, and the stable output frequency from VCO passes the two buffer amplifier to enter the frequency mixer.

b. Working Principle of VCO The Rx module employs two VCOs which cover the band of 348.35~383.35MHz and 383.35~418.35MHz

Page 12

TR850 Service Manual

(VHF is 84.35~103.35MHz and 103.35~122.35MHz) respectively, and the switch of VCO is controlled by the RXVCOSELECT sign al. VCO employs three point capacitance oscillation circu it. The VCO that covers the band of 348.35~383.35MHz (VHF is 84.35~103.35MHz) is composed of D1006~D1009、L1017、 Q1011 and some other components, while while t he VCO covers the band of 383.35~418.35MHz (VHF is

103.35~122.35MHz) is composed of D1002~D1005、L1016、Q1009 and some other components.

3.3.2. Power Section

Figure 3-8 Whole Unit Power

As Figure 3-8 shows, the whole unit power supply employs adaptive ac/dc power supply with AC priority and DC/AC auto switch. The output DC voltage which is switched and protected by the electric relay will be divided into two paths. One path is for the RF power amplification, and the other is for banseband mainboard. The switch in the front panel turns the power on/off via the electric relay U2. The protection circuit wil l c u t off all the DC output when the DC exceeds 18V.

Meanwhile, the internal DSP will send the digital audio signal which achieves t he decodin g and enc oding to the FPGA(U14) for time slot processing and finishi ng the framing, filtering and interpolation and other synchronization calculation of the data, and the digital audio signal will then be sent to the DAC (U24) via the SPI interface for the audio digital/analog switch, generating the analog speech two point modulation signal before being sent to the transmitter for the audio forwarding.

 Local Audio TRx

The internal DSP in the main processor(U4) connects to the CODEC(U30) via the I2S digital audio interface. The CODEC(U30) will convert the analog audio input from the external to digital audio, then

Page 19

TR850 Service Manual

send into the internal DSP. In the meantime, converts the received digital audio from the internal DSP to analog audio, then send t he audio t o audio pow er a mplifier( U31), be fore final ly send t o the ACCY external interface, which is to drive the 1W, 16Ω speaker.

3.3.4. Ethernet Interface

Figure 3-12 Ethernet Interface

As Figure 3-12 shows, A RMII simpli fied interface is used between the CUP(U4) and network interface chip(U17) . RMII inter fac e independent clock uses external clock mode and sh ar e 50MHz clock with U17.

CPU (U4) achieves the hardware information of internet interface U17 through the independent configuration interface MDIO. CPU also initiate it and assi gn M AC and IP address.

The data transmitt ing and receiving bet ween netw ork inter face ch ip(U17) and interface connector(J12) are achieved through connecting the transformer inside the connector jack RJ45 and LED through 2 pairs of differential line.

The network interface can realize parameter adjustment and parameter conf igure, user programming and firmware upgrade.

3.3.5. Boot Mode

A boot mode selection switch (J4) is provided on the baseband. The four position 1 to 4 of DIP encode switcher are correspondingly connected with boot 1 to boot 4 of OMAP (U4), so the boot operation mode will be changed after being powered on.

The level of position “ON” of encode switcher corresponding to boot which is connected to GND is “0”.Conversely, the level of position “OFF” is “1”.

As showing in Figure 3-13, the level of boot1 to boot4 of switcher is 0101, and it enters to firmware download mode after power on. It can upgrade the guide program and the low driver program by booting from serial port(UART2).
