摘要

本文描述了一种利用市售的束导二极管的ku波段集成电路平衡混频器。在厚度为254 μ m的17.5 μ m的RT-Duroid 5880基板上蚀刻而成，平面电路板夹在波导分块外壳的两个部分之间。由于制造精度主要取决于低蚀刻公差，因此该设计特别适合毫米波应用。在自偏置模式下，ku波段样机的转换损耗为8db, DSB噪声系数为5.6 dB，隔离值为35 dB。

An integrated Ku-band quasi-planar circuit mixer

A Ku-band integrated circuit balanced mixer using commercially available beam-lead diodes is described. Etched from a 17.5- mu m-copper cladded RT-Duroid 5880 substrate with a thickness of 254 mu m, the planar circuit board is sandwiched between the two parts of a waveguide split-block housing. Since the manufacturing accuracy mainly depends on the low etching tolerances, the design is especially suitable for millimeter-wave applications. 8-dB conversion loss, a 5.6-dB DSB noise figure, and isolation values of 35 dB are obtained for the Ku-band prototype operating in the self-biasing mode.<>
