Description

A kind of compound dielectric ceramic ring ferrite sheet miniature isolator
(1) technical field
This utility model belongs to the radio frequency in electronic information and microwave device field
(2) background technology
With the continuous development of microwave technology, microwave device is experienced by distributed constant, lumped parameter, micro-strip designing technique Deng research manufacture ferrite circulator, the process of isolator, also constantly from large to small, weight gradually mitigates the volume of device, peace Dress mode is only 5mm × 3mm × 1mm by Surface Mount installation, the external isolator having been reported that, circulator volume is mechanically fixed to, Realize the Surface Mount of circulator, isolator.
Also increasingly the appearance of miniaturization, particularly unmanned vehicle develops to microwave device with continuous for the development of airborne vehicle Volume and performance propose higher requirement, miniaturization, integration are required in volume, high reliability in performance, is required.Mesh Front development small size, high performance microwave device, the development that can be especially adapted to dual-use circulator, isolator seem special It is important.
(3) utility model content
This utility model is carried out according to invention " a kind of design and calculation method of quasi- micro-strip ferrite circulator inner wire " It is embodied as, its objective is to realize the miniaturization of product.Can be increased using the ferrite sheet with compound dielectric ceramic ring Product capacitance, so as to realize reducing the purpose of inner wire diameter by reducing the capacitance on inner wire, further subtracts Little cavity volume, realizes miniaturization, metal cover board is fixed on cavity and is more beneficial for product electromagnetic shielding performance.Intend using following skill Art scheme:Unique structure is designed with patent of invention " a kind of design and calculation method of quasi- micro-strip ferrite circulator inner wire " Quasi- micro-strip inner wire, with inner wire as line of symmetry, inner wire above and below is sequentially placed the ceramic ring ferrum with compound dielectric Oxysome piece, metal spacer, SmCo, place iron-nickel alloy temperature-compensating plate again on the SmCo of inner conductor side, inner wire, Ceramic ring ferrite sheet with compound dielectric, metal spacer, SmCo, iron-nickel alloy temperature-compensating plate press central shaft Line is placed on inside cavity, and metal spiral cover piece is screwed in above cavity, metal cover board is fixed on above cavity with bonding agent.Product Totally three ports, wherein the 3rd port is connected with Chip-R by center conductor.Chip-R is welded recessed in chamber outer surface In groove, product cavity overall dimensions are 13mm × 13mm × 7mm.
The beneficial effects of the utility model are:
1. product insertion loss is little, and power bears height, and temperature stability is good, and magnetic shield is good, compact structure, attractive in appearance.
2. product has extensively use in radar, navigation, air traffic control, mobile communication and other electronic equipments On the way, it is adapted to military and civilian dual-purpose, is particularly suitable for the unmanned plane for having strict demand to volume and weight.
