  • Page 6 CIRCUIT DESCRIPTION 3-1 GENERAL (1) FORWARD POWER DETECTOR (2) SWR DETECTOR An 8-bit microprocessor controls the AT-130/AT-130E/AT- (3) PHASE DETECTOR 140. The tuner matches the antenna system to the trans- (4) IMPEDANCE DETECTOR ceiver by using four kinds of detector circuits. These circuits are: Detailed descriptions of each circuit as follows.
  • Page 7 3-4 PHASE DETECTOR CIRCUIT 3-6 LOGIC CIRCUIT This circuit consists of L2, L3 and IC9. The phase detector’s IC1, The CPU, controls the antenna matching network. The purpose is to detect reactance components and provide a CPU receives +5V through IC8 when DC power is applied to pure resistance.
