본 논문은 상호 동기화된 Gunn 다이오드를 이용한 저잡음 8.89차 고조파 발진기를 나타낸다. 발진기의 회로 크기를 줄이기 위해 다층 MIC 기술이 채택되었습니다. 발진기는 Gunn 다이오드, 슬롯 라인 공진기 및 스트립 라인으로 구성됩니다. 슬롯 라인 공진기에 Gunn 다이오드를 내장하면 고조파 RF 신호를 매우 쉽게 생성할 수 있습니다. 스트립 라인은 전력 결합 출력 회로에 사용됩니다. 낮은 위상 잡음과 원치 않는 고조파 억제를 달성하기 위해 슬롯 라인 공진기의 모양은 정사각형입니다. 18.75차 고조파 발진기는 K 대역에서 설계 및 제작되었다. 출력 전력은 설계 주파수 2GHz(XNUMXf0) 116.2MHz의 오프셋 주파수에서 -1dBc/Hz의 위상 잡음을 갖습니다. 원하지 않는 기본 주파수 신호를 탁월하게 억제합니다(f0) -33dBc가 달성됩니다. 또한 기존에 제안된 회로에 비해 회로 크기가 XNUMX/XNUMX로 줄어들었다.

Abstract: This paper represents a low noise second harmonic oscillator using mutually synchronized Gunn diodes. A multi-layer MIC technology is adopted to reduce the circuit size of the oscillator. The oscillator consists of Gunn diodes, slot line resonators and strip lines. By embedding Gunn diodes in the slot line resonators, a harmonic RF signal can be generated very easily. The strip lines are used for the power combining output circuit. The shape of slot line resonator is square in order to achieve the low phase noise and the suppression of undesired harmonics. The second harmonic oscillator is designed and fabricated in K band. The output power is +8.89 dBm at the design frequency of 18.75 GHz (2f0) with the phase noise of -116.2 dBc/Hz at the offset frequency of 1 MHz. Excellent suppression of the undesired fundamental frequency signal (f0) of -33 dBc is achieved. Also, the circuit size is reduced by three-tenths relative to that of the previously proposed circuit.
