  • Page 3 DJ-V57 CIRCUIT DESCRIPTION [Reception] 1. RX Method: Double Conversion Super Heterodyne 1st IF: 38.85 MHz 2nd IF: 450 KHz 2. Front End [VHF] The signal input from antenna passes through the low pass filter, and then it is amplified at RF amplifier Q117. The amplified signal is led to band pass filter and band switch D132, then input to the mixer Q120.
  • Page 4 5. Squelch The AF signal from pin 9 of IC105 is input to pin 8 of IC105. The input signal is output from pin 14 of IC105 passing through the noise filter amplifier and rectifier circuits inside of IC105. The rectified signal is input to the A/D port pin 82 of microcomputer IC109.
  • Page 5 result of phase comparison, the pulse signal is output from the charge pump output of pin 21 of IC102, then the signal is converted into the DC voltage at the low pass filter and added to the cathode side of VCO vari-cap to make the phases equal.
