Abrégé
(EN)
An up-down converter comprises: a first mixer for changing an input RF (radio frequency) signal into an IF (intermediate frequency) signal using a first local signal; an IF filter for filtering the IF signal changed by the first mixer; a second mixer for changing the IF signal filtered by the IF filter into an output RF signal using a second local signal; and a local oscillator for controlling the frequencies of the first and second local signals based on the frequencies of the input RF signal.

업-다운 컨버터(up-down converter)는 입력 RF(Radio Frequency) 신호를 제1 로컬 신호를 이용하여 IF(Intermediate Frequency) 신호로 변환시키는 제1 믹서(mixer)와, 제1 믹서에 의해 변환된 IF 신호를 필터링하는 IF 필터와, IF 필터에 의해 필터링된 IF 신호를 제2 로컬 신호를 이용하여 출력 RF 신호로 변환시키는 제2 믹서, 및 입력 RF 신호의 주파수에 기초하여 제1 로컬 신호와 제2 로컬 신호의 주파수를 조절하는 로컬 오실레이터(oscillator)를 포함한다.
