摘要: 本文介紹了Ku波段寬帶機(jī)械調(diào)諧耿氏振蕩器的實(shí)用電路結(jié)構(gòu)、設(shè)計(jì)原則以及運(yùn)用雙金屬補(bǔ)償技術(shù)得到的實(shí)驗(yàn)結(jié)果。振蕩器輸出功率為50120mW;機(jī)調(diào)范圍一般為10001500MHz,最寬優(yōu)于2500MHz;頻率溫度系數(shù)一般小于0.07MHz/℃,最低優(yōu)于0.01MHz/℃;功率溫度系數(shù)一般小于0.015dB/℃,最低優(yōu)于0.007dB/℃。Abstract: The design principles and a practical circuit of a Ku-band broadband me-chanical tuning Gunn Oscillator is described The oscillator is stabilized by bimetal compen-sation. Its power output is 50 to 120mW; the mechanical tuning bandwidth is 1000 to 1500 MHz, its maximum value is 2500MHz; the typical frequency temperature coefficient is less than 0.07MHz/℃, its minimum value is 0.01MHz/℃; and the typical power temperature coefficient is less than 0.015dB/℃, its minimum value is 0.007dB/℃.
