  • Page 8 2.3.1 Overview The NX-1200 series is a VHF Analog FM & Digital Portable transceiver designed to operate in the frequency range of 136 to 174MHz. The unit consists of a transceiver IC, a transmitter, a digital control unit, and a power supply circuit.
  • Page 9 The oscillation frequency is adjusted TCXO directly by controlled the D/A converter (IC604). 2.3.5.2 • NX-1200 series There is one VCO contain TX VCO and RX VCO. The VCO (Q4) generates the carrier for the transmitter and the receiver. The VCO oscillation frequency range is 272 to 348MHz.
  • Page 10 2.3.5.3 PLL (IC2) compares the difference in phases of the VCO oscillation signal and the TCXO (X1) reference frequency. And it returns the difference voltage to the VCO CP terminal and realizes the "Phase Locked Loop". This allows the VCO oscillation frequency to accurately match (lock) the desired frequency.
  • Page 11 2.3.7 Power Supply Circuit The battery voltage (+B) is provided from battery terminal. The battery voltage passes through the 3.15A fuse (F400), and goes to RF Drive and final amplifier, DC/DC converter (IC407), AF amplifier (IC300 through the 1.0A fuse (F300)), and INT DET IC (IC406). IC406 monitors battery voltage.
