介质绝缘交迭的微波非互易结
DIELECTRIC-I NSULATED CROSSOVER FOR MICROWAVE NON-RECIPROCAL JUNCTION
-
摘要: 正 利用集成工艺,Knerr等人首先研制成功L波段薄膜型集总元件的铁氧体环行器。其后,很多人用稍异的工艺,以类似的结构,相继做出性能良好的同类器件。薄膜型集总元件环行器的电路示意图见图1,其核心部分是一个非互易结。这个结是由在一块抛光的微波铁氧体基片上,采用绝缘交迭工艺制造成的三个互相交迭、彼此绝缘、并相间120的电感线圈所构成。图1示出的12个相互交叉交迭点是分别用ZrO2空气双层介质或单层空气介质作绝缘隔离层制成的。前者工艺过于繁难,后者则使器件承受不了较大

Abstract: A simple technology of dieleetric-insulated crossover for the interwoven intercon-ductors of microwave non-reciprocal junction made of ferrite material is presented. It is aimed at simplifying the complicated processes by using the ZrO2-air double layers or air single layer insulated crossover technology. A crossover sample has been fabricated. It has good electrical and mechanical.characteristics and is applicable to fabrication of film mode lumped-element ferrite devices. -
