摘　　要：宽频带晶体检波器采用混合集成工艺，用热压键合的方法把低势垒肖特基检波二极管的管芯焊接在微带电路上。整个电路制作在一个４ｍｍ×１２ｍｍ×０．３ｍｍ的三氧化二铝陶瓷基片上，并安装在一个圆柱型８．５ｍｍ×３５ｍｍ金属盒体内。射频联接应用ＳＭＡ接头，配有ＳＭＡ—Ｎ型转换接头。为了获得平坦的频率响应和低的输入驻波比，采用了一个Ｒ—Ｌ并联支路和“Ｔ”型匹配网络，从而使检波器在０．０１～１８ＧＨＺ频带内驻波比＜１．５，频率响应起伏＜±０．５ｄＢ，采用的Ｒ—Ｌ并联支路和“Ｔ”型网络亦可用于其它微波电路，以改善微波部件的性能。A hybrid integration technology is given here for the broadband crystal detector.A low barried Schotty diode is welded on microstrip circuit on a 4mm×12mm×0. 3mm Al2O3 pottery chirp by hot pressing. The whole circuit was assembled in a metal box of 8.5mm ×35mm. SMA Conector and SMA--N adaptor were employed in RF conecting. R-L shunt circuit and T network were employed to attain frequency fluctuation less than±0.5dB and VSWR less than 1.5 over 0.01￣18 GHz frequency band. These technology can be applied to the other microwave circuit to improve the performance of the microwave component.
