Abstract
This paper deals with the self-excited mixer using tunnel diode oscillator operated as a microwave source and Doppler signal detector. The system impedance, the oscillation condition and the frequency conversion theory including moving target are investigated. The oscillating frequency and the output of tunnel diode oscillator are 2.035 GHz and 0.1 mW. The input signal frequency which is equivalent to Doppler signal is lower than tunnel diode oscillator frequency by 125 MHz. TDe conversion loss has been investigated as a functicn of input signal level. This loss is greater than 67 db for the large pump mode.
티넬다이오드를 마이크로 웨이브 발진기로 동작시키면서 출력이 복사되어 이동물체에서 반사할때 변화신호를 티넬다이오드에 주입하여 부성저항영역에서 혼합시키는 경우 이동물체를 포함하는 전체계의 임퍼턴스와 발진조건, 주파수 변환 이론을 고찰했다. 터넬다이오드름 2.035GHz, 0.1mw로 발진시키고 이동물체반사신호와 등가인 신호발생기는 125MHz 낮게 발광시켰다. 입연신호크기에 따른 변환손실은 대신호주입 경우 약 67db였다.
