FCC ID: K6610334720 IC ID: 511B-10334720 Circuit Description 1/3 Vertex Standard Co., Ltd. VX-920/970 (UHF) series Circuit Description 1. Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency (IF) of 50.85MHz and a second IF of 450kHz. Incoming signal from the antenna is mixed with the local signal from the VCO/PLL to produce the first IF of 50.85MHz. This is then mixed with the 50.4MHz second local oscillator output to produce the 450kHz second IF. This is detected to give the demodulated signal. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the microphone. It is then amplified and sent to the antenna. 2. Receiver System 2-1. Front-end RF amplifier Incoming RF signal from the antenna is delivered to the RF Unit and passes through Low- pass filer, antenna switching diode, high pass filter and removed undesired frequencies by varactor diode (tuned band-pass filer). The passed signal is amplified in Q1022 and moreover cuts an image frequency with the tuned band pass filter and comes into the 1st mixer. 2-2. First Mixer The 1st mixer consists of the Q1034, T1001, T1002 and T1003. Buffered output from the VCO is amplified by Q1033 to provide a pure first local signal between 399.15 and 461.15MHz for injection to the first mixer. The IF signal then passes through monolithic crystal filters XF1001 (±5.5 kHz BW) to strip away all but the desired signal. 2-3. IF Amplifier The first IF signal is amplified by Q1058. The amplified first IF signal is applied to FM IF subsystem IC Q1067 which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and S-meter amplifier. The signal from reference oscillator X1003 becomes 3 times of frequencies in Q1067, it is mixed with the IF signal and becomes 450KHz. The second IF then passes through the ceramic filter CF1001 (wide channels), CF1002 (narrow channels) to strip away unwanted mixer products, and is applied to the limiter amplifier in Q1067, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001. 2-4. Audio amplifier Detected signal from Q1067 is inputted to Q1032 and is output through the band path filter inside Q1032. In the case an optional unit is installed, the Q1078 is made OFF and the AF signal from Q1032 goes the optional unit. In the case an optional unit is not installed, Q1078 is made ON and the signal goes through Q1078. The signal then goes through de-emphasis part and expander Q1023. When the function of expander is off, the signal will be bypassed by Q1016. The output signal of expander (or a signal from de-emphasis) goes through AF mute switch Q1078 and amplified by Q1077. The signal goes to Q1030, when the audio equalizer is off. In the case the audio equalizer is on, the signal from Q1077 goes to the buffer amplifier Q1077 for audio equalizer Q1083, Q1025 and Q1029. And then the signal goes to Q1030. The output from Q1030 is amplified with AF power amplifier Q1015 after passing AF volume Q1020. The output of Q1015 drives a speaker (it chooses the external SP or internal SP in external terminal, SELECT) 2-5. Squelch Circuit There are 13 levels of squelch setting from 0 to 12. The level 0 means open the squelch. The level 1 means the threshold setting level and level 11 means tight squelch. From 2 to 10 is established in the middle of threshold and tight. The bigger figure is nearer the tight setting. The level 12 becomes setting of carrier squelch. FCC ID: K6610334720 IC ID: 511B-10334720 Circuit Description 2/3 Vertex Standard Co., Ltd. 2-5-1. Noise Squelch Noise squelch circuit is composed of the band path filter of Q1067, noise amplifier Q1071, and noise detector D1047, D1048. When a carrier isn't received, the noise ingredient which goes out of the demodulator Q1067 is amplified in Q1071 through the band path filter Q1067, is detected to DC voltage with D1047, D1048 and is inputted to 16pin (the A/D port) of the Q1069 (CPU). When a carrier is received, the DC voltage becomes low because the noise is compressed. When the detected voltage to CPU is high, the CPU stops AF output with Q1078 "OFF" by making the 59pin (CPU) "L" level. When the detection voltage is low, the CPU makes Q1078 ON with making 59pin "H" and the AF signal is output. 2-5-2. Carrier Squelch The CPU (15pin: A/D port) detect RSSI voltage output from Q1067 12 pin, and controls AF output. The RSSI output voltage changes according to the signal strength of carrier. The stronger signal makes the RSSI voltage to be higher voltage. The process of the AF signal control is same as Noise Squelch The shipping data is adjusted 3dB higher than squelch tight sensitivity. 3. Transmitter System 3-1. Mic Amplifier The AF signal from internal microphone J1001 4pin or external microphone J1001 19pin is amplified with microphone amplifier Q1076, after microphone selection switch Q1001, and passes microphone gain volume Q1020. The AF signal which was controlled in the correct gain passes compressor Q1023. When not using a compressor, with the control from the CPU, it passes in the compressor circuit inside of Q1023 and it is output and it passes a pre-emphasis circuit. Q1078 becomes OFF when an option unit is attached and the AF signal from Q1023 goes via the option unit. When an option unit isn't attached, Q1078 becomes ON, the signal passes Q1078 and is input to the pre-emphasis amplifier Q1032. The signal passed limiter and splatter filter of Q1032 is adjusted by maximum deviation adjustment volume Q1020. The adjusted low frequency signal ingredient is amplified by Q1075, added modulation terminal of TCXO (X1003), the FM modulation is made by reference oscillator. The high frequency signal ingredient is amplified Q1075, and adjusted the level by volume Q1020 to make frequency balance between low frequency. After that, it is made FM modulation to transmit carrier by the modul…
