Abstract

イメージリジェクションミキサにおいて、入力端子に第１無線周波数帯の信号が入力された場合、第１混合器および第２混合器が、入力された第１無線周波数帯の信号を局部信号発振部からの第１局部信号を用いて第１中間周波数帯の信号に変換し、フィルタ回路が、第１中間周波数帯に存在するイメージ妨害信号を第１減衰帯域で減衰する。また、入力端子に第２無線周波数帯の信号が入力された場合、第１混合器および第２混合器が、入力された第２無線周波数帯の信号を局部信号発振部からの第２局部信号を用いて第２中間周波数帯の信号に変換し、フィルタ回路が、第２中間周波数帯に存在するイメージ妨害信号を第１減衰帯域より狭帯域の第２減衰帯域で減衰する。
