Zusammenfassung:PURPOSE: A broadband radar detector by employing a saturated regional operation amplifier is provided to drastically improve the broadband receiving performance of the radar detector by designing the radar detector circuit in accordance with the present invention employing the amplifier to operate the local oscillation frequency to the saturated region. CONSTITUTION: A broadband radar detector by employing a saturated regional operation amplifier includes an antenna(10) for receiving a frequency, a first local oscillator(20) for generating a frequency variable signal, a first amplifying block(200) for amplifying the signal outputted from the first local oscillator(20), a first filter block(30) for removing a noise signal generated from the first local oscillator(20), a second amplifying block(300) for amplifying the signal noise filtered through the first filter block(30) a first mixing block(40) for mixing the signal transmitted through the first amplifying block(200) and the frequency variable signal generated at the first local oscillator(20), an amplifying block(50) for amplifying the frequency signal mixed by the first mixing block(40), a second local oscillator(60) for generating a frequency to modulate the frequency signal passed through the amplifying block(50), a second mixing block(70) for mixing the frequency generated at the second local oscillator(60) and the frequency signal passing through the amplifying block(50), a second filter block(80) for obtaining only a signal having a specific band width passing through the second mixing block(70), a demodulator(90) for analog to digital converting the frequency signal filtered with a specific frequency through the filter block, a main control block(100) for implementing an appropriate control of the elements, a function operational block(110) for implementing a function operation of the radar detector and a display panel(120) for recognizing to a user during the detection of the specific signal. 본 발명은 특정신호의 검출을 위한 레이더디텍터로서, 초고주파를 수신하기 위한 안테나와; 주파수를 발생시키는 제1국부발진부와; 상기 제1국부발진부에서 출력된 신호를 증폭하기 위한 제1증폭기와: 상기 제1증폭기를 통해 증폭된 신호에서 노이즈를 제거하기 위한 제1필터부와; 상기 제1필터부에 의해 노이즈 필터링된 신호를 다시 증폭하기 위한 제2증폭기와; 상기 안테나로부터 수신된 초고주파를 주파수변환하기 위해 상기 제1국부발진부에서 발진된 주파수와 혼합하기 위한 제1혼합부와; 상기 제1혼합부에 의해 혼합된 주파수를 증폭하기 위한 증폭부와; 상기 증폭부를 통과한 주파수 신호에 혼합할 주파수를 발생시키는 제2국부발진부와; 상기 제2국부발진부에서 발생한 주파수와 상기 증폭부를 통과한 주파수 신호를 혼합하기 위한 제2혼합부와; 상기 제2혼합부를 통과한 주파수 신호의 특정 대역신호만을 얻기 위한 제2필터부와; 상기 제2필터부를 통해 특정 대역으로 필터링된 주파수 신호를 A/D변환하기 위한 복조부와; 상기 복조된 신호를 입
