Description
Claims (3)
- 基地局の増幅器から出力される送信信号の進行波電力と、増幅器の出力側から反射される信号の反射波電力と、をそれぞれ測定する電力検波回路において、
増幅器の出力部に設けられ、進行波と反射波とを弁別する弁別手段と、
進行波電力と反射波電力との立ち上がり特性をそれぞれ調整し、これらの立ち上がり特性を一致させる調整器と、
立ち上がり特性が調整された進行波と反射波とを切り替える切替器と、
切替器からの電力を検波する1つの電力検出器と、
切替器の切り替えタイミングを指示すると共に電力検出器による検波電力を測定する制御器と、
を備えることを特徴とする電力検波回路。 - 請求項1に記載の電力検波回路において、
制御器は、測定された検波電力と、予め設定された各しきい値とを比較した結果を上位の制御装置に出力することを特徴とする電力検波回路。 - 請求項1または2に記載の電力検波回路において、
制御器は、進行波電力測定と反射波電力測定とに対して予め決められた測定比率により切替器の切り替えタイミングを制御することを特徴とする電力検波回路。
