Abstract

　TDD方式等の無線送受信装置において、所定の送信期間中に送信側で送信信号を検出し、該送信期間中に、アンテナからサーキュレータを経て反射して来た信号を受信側で検出し、さらに所定の受信期間中には該受信側から受信信号を検出する。この場合、該送信期間の一部において該送信側回路から検出した送信信号を選択し、該送信期間の残部においてアンテナからサーキュレータを経由して該受信側で検出した反射信号を選択し、そして該受信期間においてさらにアンテナからサーキュレータを経由して該受信側で検出した受信信号を選択して出力することができる。または、該送信期間において該送信側から反射信号を検出し、該送信期間において該送信側から送信信号を選択出力し、該受信期間において該受信側から受信信号を選択出力してもよい。送信信号と反射信号とで定在波比VSWRを演算する。
