据《信学技报》(日)2009年109(109)期报道,日本佐贺大学研究了耿氏二极管高次谐波振荡器的低噪声技术。新开发的振荡器由slot line谐振器、耿氏二极管和微带线构成。通过平面电路设计使电路简易化和小型化,振荡器由原来的圆形改变为方形。4只耿管在偏压9 V、偏流230 mA测试时,高次谐波18.75 According to “Letters Science and Technology” (Japan) 2009 109 (109) reported that Japan’s Saga University, Gunn diode high-harmonic oscillator low-noise technology. The newly developed oscillator consists of a slot line resonator, Gunn diode and microstrip line. Through the planar circuit design to make the circuit simple and small, the oscillator from the original round to square. Four Geng tubes were biased at 9 V with a bias current of 230 mA. The higher harmonics were 18.75
