7.THEORY OF OPERATION Circuit Compositions and Operation Theory The basic explanation for the circuit composition the one board controlling the analog circuit parts and the digital circuit parts. Receiver Transmission parts are composed in the double conversion system, which has the 1st IF Frequency of 10.7 MHz and 2nd IF Frequency of 450 kHz. With the saw filter, which has an excellent band characteristic and sharp characteristic, the 2 poles CF used in the 1st IF, and the sensitivity repression is reduced for the more stable reception. RF Front end The signal received by the antenna will be transmitted to the band pass filter through the antenna switching circuit consisted of LT1, LR1, CT1, CT2 and CT3. The front RF amplifier transistor QR1 consists of the saw filter and input/output band pass filter. Saw filter has the bandwidth of approximately 5 MHz, primarily diminishes the other signal rather then the 1st IF image and other signal within the reception band and amplifies only the necessary signal within the RF. 1st Mixer The receiver signal, which has been amplified in the RF fronted, is provided to the base of the 1st mixer QR2. The 1st L/O signal provides from the VCO is supplied to the emitter of QR2 and converted to the 1st IF 10.7 MHz. 1st IF Filter and 1st IF Amplifier The signal converted by QR2 to 10.7 MHz, the 1st frequency, change its impedance through CR8, LR6 and then is infused to the fundamental CF which has the center frequency of 10.7 MHz and the width of +/- 30 kHz. Here, the signal reduces the image and other unwanted signal for the 2nd IF. Then the signal is infused to the IC3. The IC3 which functions as the 2nd mixer, the 2nd IF amplifier, and the FM detector, RSSI, PREMIC, compander, PLL circuit. 2nd Mixer, and IF, FM Detector The receiver IF signal of 10.7 MHz, which has been infused to IC3 is mixed with the 2nd L/O signal of 10.250MHz, and converted to 450 kHz, the 2nd IF frequency. The receiver signal converted to the 2nd IF frequency passed through the F3, the ceramic filter of 450 kHz again. After the limiting inside the IC3 and the FM demodulating by the quadrature detector inside the IC3, the signal offers the output through the 21 th pin of IC3. The 2nd L/O signal of 10.250MHz, which infused to the IC3 filters and uses directly the crystal of 10.250 MHz. The squelch circuit is composed to detect the noised from the received signal demodulate in the 31 th pin of the IC3. For this purpose, the noise filter is using the OP amplifier inside the IC3. Transmitter The transmission parts of the PR-3175 are designed to amplify the RF signal oscillated and modulated by the synthesizer to approximately 2(0.5) W by the power transistor of QT3. TX Power (QT3) The transmitted signal of approximately 2(0.5)W, combined at the driver TR is supplied to the base of the QT3 amplifier. The transmitted signal amplified to 2W here passes the TX LPF of the 2nd characteristic of the LT2 and the LT3, and RX/TX switching takes place by the DT1. After this, the signal is provided to the antenna the TX LPF of the 1st characteristics, consisted of the LT1. Frequency Synthesizer Voltage Control Oscillator (VCO) The VCO of oscillates 462.5625 MHz to 467.7125 MHz under the transmission condition and 451.8625 MHz to 457.0125 MHz under the reception condition. The VCO consists of the clip oscillator of the QV1, and contains the oscillator frequency of approximately 10.7MHz during the transmission/reception conversion. That is since the VCO should oscillate relatively low frequency during reception compared to transmission, the DV2 is directly biased by the QV2. Therefore as a result, the CV8 is added in parallel to the resonance circuit of the VCO to oscillate a low frequency. During transmission, a relatively high frequency should be oscillating compared to reception. Therefore, the DV2 is adversely biased by the QV2, and as a result, the CV8, which is added unparallel to the circuit of the VCO is removed to oscillate the desired transmission frequency. PLL Part of the IC3 controls the VCO in order to oscillate the accurate frequency. The output frequency of the VCO is supplied to the 44 th pin of IC3. At the IC3, TCXO(10.250MHz) by the TCXO-1 is compared to the output frequency of the VCO. The VCO is controlled the loop filter consisted of the RM32, RM33, RM34, and the CM14, in order to oscillate the stable frequency wanted for the radio. The VCO controlled voltage which has passed the loop filter is supplies to the DV1 varactor diode, and the VCO an oscillate the PLL programmed frequency by the capacity variation in the DV1. In addition, the LV2 on the VCO circuit function as frequency for the VCO to be properly controlled. RX/TX Buffer Amplifier (QB1) The RF signal oscillate at the VCO is provide to the QR2 RX 1st mixer through the QB1 during the reception, and is provide to the QT2 power driver amplifier through the QT1 during the transmission. PLL Frequency Synthesizer (IN 6311) The PLL synthesizer of the signal loop PLL circuit with the reference of 6.25 kHz. The IC3 includes all the function such as the reference oscillator, the driver, the phase detector, the lock detector, and the programmable divider. At the reference oscillator, the 10.250 MHz TCXO of the TCXO is connected to the pin 52,53 of the IC3 to oscillate the frequency of 10.250MHz. The TCXO (10.250MHz) is the temperature compensation circuit to maintain the frequency within the allowable error range even under a low temperature of -20. The phase detector sends out the output power to the loop filter through 44 pin of the IC3. IF the oscillation frequency of the VCO is low compared to the referenced frequency, the phase detector sends out the output power in positive pulse. If the oscillation frequency of the VCO is high, phase detector send out can maintain the frequency set. The programmable divider maintains the desired frequency with control from the CPU. The dividing ratio, "N" to oscillate the desired frequency…
