介質(zhì)絕緣交迭的微波非互易結(jié)
DIELECTRIC-I NSULATED CROSSOVER FOR MICROWAVE NON-RECIPROCAL JUNCTION
-
摘要: 正 利用集成工藝,Knerr等人首先研制成功L波段薄膜型集總元件的鐵氧體環(huán)行器。其后,很多人用稍異的工藝,以類似的結(jié)構(gòu),相繼做出性能良好的同類器件。薄膜型集總元件環(huán)行器的電路示意圖見圖1,其核心部分是一個非互易結(jié)。這個結(jié)是由在一塊拋光的微波鐵氧體基片上,采用絕緣交迭工藝制造成的三個互相交迭、彼此絕緣、并相間120的電感線圈所構(gòu)成。圖1示出的12個相互交叉交迭點是分別用ZrO2空氣雙層介質(zhì)或單層空氣介質(zhì)作絕緣隔離層制成的。前者工藝過于繁難,后者則使器件承受不了較大

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. -
