Abstract
광 다이나믹 레인지에 걸쳐 다단이고 고정밀도.고안정하게 출력 레벨을 변화시킬 수 있고, 연속 신호.버스트 신호의 양쪽에 대응할 수 있는 파워 컨트롤 회로를 제공한다. 송신 신호를 증폭하고, 그 증폭율을 제어 전압으로 가변시킬 수 있는 파워 앰프 회로(101)과, 상기 파워 앰프 회로에서 증폭된 송신 신호의 출력 레벨을 모니터 하는 커플러(102)와, 커플러 출력을 입력하여 모니터 검파 전압을 생성하는 검파 회로(103)과, 상기 검파 전압과 제어 회로(105)의 지시에서 발생된 기준 전압 출력의 비교에 의해 오차 증폭하는 오차 증폭 회로(104)에서 제어 전압을 생성하고, 이것을 상기 파워 앰프 회로에 공급하는 파워 컨트롤 회로에 있어서, 커플러와 검파 회로의 사이에 모니터 출력 신호를 제어 회로로부터 지시된 이득으로 증폭하는 가변 게인 앰프(106)과, 검파 회로와 오차 증폭 회로 사이에 제어 회로에 의한 지시에 의해 검파 전압을 통과 및 유지시키는 샘플.홀드 회로 (107)을 설치한다.Provides a power control circuit that can vary output levels stably and with high accuracy and stability over a wide dynamic range and can cope with both continuous and burst signals. A power amplifier circuit 101 capable of amplifying a transmission signal and varying its amplification rate to a control voltage, a coupler 102 for monitoring the output level of the transmission signal amplified by the power amplifier circuit, and a coupler output Generating a control voltage by a detection circuit 103 for generating a monitor detection voltage and an error amplification circuit 104 for error amplifying by comparison of the detection voltage with a reference voltage output generated at the instruction of the control circuit 105. In the power control circuit for supplying this to the power amplifier circuit, the variable gain amplifier 106 amplifies the monitor output signal with the gain indicated by the control circuit between the coupler and the detection circuit, and between the detection circuit and the error amplifier circuit. Sample and hold circuits 107 are provided to pass and hold the detected voltage by the instruction by the control circuit.
