Beschreibung
Zusammenfassung:	The present invention relates to a down converter comprising: a first frequency mixer for converting a high frequency signal into a first signal; and a second frequency mixer for converting the first signal into a second signal, wherein the second signal can be a signal generated based on a down-mixed signal obtained by mixing the first signal and a signal output from a local oscillator through the second frequency mixer. 하향 주파수 변환기에 관한 것이며, 하향 주파수 변환기는 고주파수 신호를 제1 신호로 변환시키는 제1 주파수 믹서; 및 상기 제1 신호를 제2 신호로 변환시키는 제2 주파수 믹서를 포함하되, 상기 제2 신호는, 상기 제1 신호와 국부발진기로부터 출력된 신호를 상기 제2 주파수 믹서를 통해 혼합한 다운 믹싱된 신호에 기초하여 생성된 신호일 수 있다.
