Zusammenfassung:The present invention relates to a frequency 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 may be a signal generated on the basis of a down-mixed signal in which the first signal and a signal output from a local oscillator are mixed through the second frequency mixer. La présente invention concerne un convertisseur abaisseur de fréquence, comprenant : un premier mélangeur de fréquence pour convertir un signal haute fréquence en un premier signal ; et un second mélangeur de fréquence pour convertir le premier signal en un second signal, le second signal pouvant être un signal généré sur la base d'un signal mélangé à la baisse dans lequel le premier signal et une sortie de signal en provenance d'un oscillateur local sont mélangés par l'intermédiaire du second mélangeur de fréquence. 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.
