DP770 Service Manual

The transmitter circuit includes three parts:

• Tran smitter Power Amplifier

T

he carrier signal generat ed by the TX VCO is mod ulate d and a mpl ified, and f eeds to t he tr ansm itter circuit

via the following steps. Step1: The signal passes a Π-type attenuator, realizing segregative isolation between RF power amplifier

circuit and TX VCO. Step2: The signal are pre-amplified by a pre-driver amplifier (UHF: Q301, VHF: Q72), providing further

segregative isolation bet ween itself and the next level amplifier. Step3: The signal goes to the next pre-am plifier and drive amplifier (RD01) to obtain further amplification,

guarantying to provide enough driver power signal to the final-stage amplifier (RD07) and obtain the final power amplification..

Step4: After amplified by multiple amplifiers, the transmitter signal is processed by a microstrip line to complete output impeda nce match ing at the output of f inal-sta ge amplifier, to reduce the output loss caus ed by impedance mismatch.

Step 5: The transm itt er signal goes through the RX/TX switch and enters to the low-pass filter.

• Low-pass Filter Circuit of suppressing t he harmonics

The low-pass filter is high-grade low-pass filter composed of lumped-parameter inductors and capacitors. By this filter, the spurious signal within the stop band can be attenuated as much as possible while the in-band ripple is within the required range.

• Auto Power C ont rol Circuit (APC includes temperature detection circuit

I

n the auto power control and temperature detection circuit, the drain current from the driver amplifier and

)

final-stage amplifier is converted to voltage via the sampling resistor and subtraction circuit which is composed of the first operat ional amplifier.

This voltage is compare d w ith the APC control voltage of output by DA C at the seco nd o perati ona l ampl ifier. Then the error voltage controls TX power by controlling the bias voltage at the gate of amplifier (including the driver amplifier and the final-stage amplifier. The temperature sensor IC detects the surface temperature of the final-stage amplifier, and converts it to DC voltage. Then the DC voltage is compared with the voltage correspo nding to t he protectio n temper ature (generally 80% of the extreme temperature ) of the amplifier. If the temperature is too high, the b ias v oltage o f the a mpl ifier w ill be redu ced unt il the sur fa c e temperature falls below the prot ec t io n temperature.

• Receiver Front-end

The HF signal from the lo w-pass filter passes through the electrica lly t unab le band-pass filter controlled via APC/TV1 level, to remove out-of–band interference signal and to send wanted band-pass signal to the low-noise amplifier (UHF:Q205,VHF:Q62). The amplified signal goes to a band-pass fi lter controlled via TFV level to remove out-of-band inter ference si gnal generat ed during a mplificat ion, and to send wante d HF signal to the mixer (UHF:Z201,VHF:Z10).

Meanwhile, the first local oscillator signal generated by VCO passes through the low-pass filter and also goes to the mixer (UHF: Z201, VHF: Z10). In the mixer, the wanted signal and the first local oscillator are mixed to generate the first IF signal (UHF: 73.35MHz, VHF: 51.65MHz). The signal passes a frequency selective network composed of LC, to suppress carrier other than the first IF signal , and to increase the isolation between the mixer and the IF filter. After that, the first IF signal i s processed by the crystal filter (UHF: Z202, VHF: Z11) and is sent to the two-stage IF amplifier circuit composed of 2SC5006 for amplification. Then the amplified signal goes to the IF processor AD9864 (UHF: U201, VHF: U91) for processing.

• eceiver Back-end

he first IF signal (73.35MHz) output by the IF amplifier goes into AD9864 (UHF: U201, VHF: U91) via Pin

T 47 and completes the second mixer, where the signal is converted to the second IF signal (2.25 MHz). The second IF signal is converted to digital signal via ADC sampling, and output via the SSI interface. Finally, the digital signal is sent to DSP (OMAP138) for demodulation.

AD9864 employs reference frequency of 12.8MHz. The second local oscillator is composed of an external oscillator, a varactor and some other components, to provide the (UHF: 71.1MHZ, VHF: 49.4MHz)

71.1MHz LO signal. The 18MHz clock input frequency of AD9864 is generated by the LC resonance loo p.

3.1.3. Frequency Generation Unit

Figure 3-5 Frequency Generation Circuit Diagram

Page 9 of 102

DP770 Service Manual

The frequency generation circuit is composed of VCO and PLL. It is the core module of the whol e TX-RX system. This circuit provides accurate carrier frequency during transmission; and provides stable local oscillator signal during rec ept ion. It has a direct influence on the performance of the system.

• Workin g Pr inciple of PLL

The 12.8MHz frequency generated by the reference crystal oscillator goes to PLL for division, generating the reference frequency (i.e step frequency f1). The frequency generated by VCO is filtered harmonic via LPF and generates another frequency ( f2) through the freq uency div ider in PLL. Then freque ncies f1 an d f2 are compared in the phase detector (PD), to generate continuous pulse current. The pulse current goes to the loop filter for RC integration and is then converted to CV voltage. Then the CV voltage is sent to the varactor of VCO. It adjusts the output f requency of VCO directly unti l the CV voltage becomes constant. Then the PLL is locked, and the stable frequency output by VCO goes to the TX-RX channel af ter passing through two buffer a m pl ifiers.

• Workin g pr inciple of VCO

Voltage controlled oscillator applies oscillation mode of three-point capacitance, and gains different output frequency through changing controlled voltage (C V) o f varactor. Rx VCO is composed of oscillating circuit and Q24/Q29 and provides local oscillati on signal. Tx VCO is composed of oscillating circuit and Q27/Q28 and provides carrier of Tx signal.

Working principle employs colpitts oscillator circuit (the RX oscillator circuit is composed of D102, D103, D106, D107 and L112 (VHF:D32, D33, D36, D34 and L23); the TX osci lla tor ci rcui t is com posed of D108, D109, D110, D101and L117 (VHF:D38, D39, D40, D41 and L31). It obtains different output frequencies by changing control voltage of varactor (i.e.CV voltage).RX VCO is composed of oscillator loop and Q104 (VHF:Q43), providing local oscillator signal. TX VCO is composed of oscillator loop and Q108 (VHF Q4 4) and provides carrier of TX signa l.

• Two-point Modulation

To obtain higher modulatio n acc uracy and lower 4 F SK b it err or, it employs two-point modu lat ion tec hno logy in the TX mode. MOD1 and MOD2 send the modulation signal to the modulation end of VCO and the reference crystal oscillat or of PLL respectively to modulate TX VCO and the reference crystal oscillator.

3.1.4. GPS Circuit

Figure 3-6 GPS Circuit Diagram

The GPS function is realized via REB-1315LPx (GPS module).The GPS module integrates a baseband processor, a LAN and a SAW . The GPS function is realized via the foll ow ing steps:

Step1: The 1575.42MHz GPS signal is received by the antenna, and then goes to HPF to remove the in-band signals used for t r ansmission and reception.

Step2: The signal goes to GPS module for amplification and filtering after frequency selection via filter. Then it will be sent to baseband section for cal culation.

Step3: The calculated GPS position information is sent to OMAP for processing via the UART interface. Meanwhile, OMAP138 can send appropriate command information to the GPS module via the UART interface.

Step4: Finally, the OMAP sends the proce ssed data information to the LCD.

3.2. Baseband Section

3.2.1. Power Section

Figure 3-7 Power Section Diagram

The radio adopts 7.4V li-i

on battery as power supply. The baseband and RF circuit are supplied by independent power structure. The baseband power is composed of two stage conversion circuit. The first stage reduces the batter y voltage to 5V by DC/DC, and the second stage converts the 5V voltage to power required voltage for the system by the power management.

Power On/Off: Power On/Off is implemented through a PMOS component. When the Power On/Off key i s pressed, PWR_Key signal becomes high level, and PMOS component becomes conducted. The system will begin initialization and set Soft_ctr to be high level. Thus, the radio is powered up. During the power off process, when the system detects that the Power On/Off key is pressed, the system will begin executing the shut down operations, and finally set Soft_ctr to be low level, which will shut down the PMOS component, thus the radio being powered off.

but no voice.

A．The frequency settings may be different from others. Set your TX/RX frequencies to be the same as others. B．The CTCSS/CDCSS signaling may be different from others. Set your CTCSS/CDCSS signaling to be the same as others. C．Your place may be too far away from the others, beyond the radio’s coverage area.

A．The antenna may get looser or may be improperly installed. Re-inst all the ant e nna. B．The frequency settings may be different from others. Set your TX/RX frequencies to be the same as others. C. Your place may be too far away from the others, beyond the radio’s coverage area.

A．Check whether the volume is smallest or not. If so, increase the volume. B．Check whether the speaker is broken or not. If so, change the s peaker.

5 GPS cannot locate your position.

DP770 Service Manual

A. Check whether the antenna is GPS+UHF dual band or not. If not, use a GPS+UHF dual band antenna to replace the old one. B. Check whether the GPS setting is correct or not. If not, set it correctly. C. Maybe there is some other RF interference around the radio’s place. Go to an open sky place and try again.

6

CPS programming failed.

A．Connection between the radio and PC is not good enough. Check and try again. B．Earphone interface board has poor contact with external programming cable. If so, change the Earphone interface board.
