Description
Technical field
This utility model relates to a kind of heavy-power circulator.
Background technology
Circulator is the incidence wave by entering its either port, multiport device according to the direction incoming next port of order determined by quiet bias field, the type of circulator has multiple, is divided into junction type circulator, Faraday rotation circulator, differential phase shift formula circulator etc. by operation principle.Other circulator relatively, junction type circulator can be taken into account small size and powerful requirement, also have advantages such as little, bandwidth, Technical comparing maturation are lost.Junction type circulator is divided into again lumped parameter formula and distributed constant formula by parameter.Lumped parameter is only applicable to microwave low-frequency range (pattern-band).Distributed constant band line style circulator can meet C-band demand, and this kind of circulator can be divided into again High-Field and low field by operation class (of an amplifying stage), and High-Field means that the direct current biasing field used is higher than the magnetic field needed for resonance absorption；Low field means that the direct current biasing field used is less than the magnetic field needed for resonance absorption.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of heavy-power circulator, and circulator volume is little for this, it is light to install, and has temperature and magnetic compensation characteristic, and power capacity is high, operating temperature range width, and temperature performance is good.
The purpose of this utility model is achieved through the following technical solutions: a kind of heavy-power circulator, and it includes cavity, magnetic circuit plate, permanent magnet, center conductor, ferrite gyromagnet sheet and cover plate, and magnetic circuit plate is arranged around the side of cavity, forms closed magnetic circuit；By cover plate in cavity, it is disposed with temperature-compensating sheet, magnetic compensation sheet, permanent magnet, ground strip, ferrite gyromagnet sheet, conductor centered by two panels ferrite gyromagnet sheet center up and down, cavity is divided into laterally zygomorphic upper cavity and lower chamber composition, center conductor is arranged on upper and lower cavity junction, center conductor changeover portion is had between ferrite gyromagnet sheet top and cavity top, one or more layers medium it is filled with in center conductor changeover portion, described cover plate is divided into upper and lower two-layer, is fixed to cavity by screw.
Described medium is PTFE medium.
It is provided with rubber seal between described cavity up and down.
The beneficial effects of the utility model are: a kind of heavy-power circulator, and circulator volume is little for this, it is light to install, and has temperature and magnetic compensation characteristic, and power capacity is high, operating temperature range width, and temperature performance is good.
