    3 - 1 section 3 circuit description 3-1 general an 8-bit microprocessor controls the at-130/at-130e/at- 140. The tuner matches the antenna system to the trans- ceiver by using four kinds of detector circuits. These circuits are: (1) forward power detector (2) swr detector (3) phase detector (4) impe...

    3 - 2 3-4 phase detector circuit this circuit consists of l2, l3 and ic9. The phase detector’s purpose is to detect reactance components and provide a pure resistance. The output of ic9 is a reference voltage of approximately 4 v when the load of l3 is a pure resistance with no reac- tance. An induc...
