The utility model relates to an embedded type surface mounted small-sized circulator, which can shorten dimension to 1/2 inch, and has the characteristics of excellent magnetic circuit closure and small magnet leakage owing to taking measures of the integrated structure of the cavity, the upper surface and lower surface magnetization of the ferrites and the surface silver plating of components, can press tightly the magnetic conduction cavity with the magnetic conduction cover plate through threads, can be installed without bonding agent and screws, has high reliability and excellent whole performance of the components, and is widely applied in the microwave communications, especially in a 3G communication system.
Description
Technical field
The utility model relates to a kind of circulator, the duplexer or the multiplexer that use in the travelling carriages such as the base station of particularly a kind of TD-SCDMA system and mobile phone, and the built-in small Surface Mount circulator that plays effects such as isolation or decoupling, belong to the microwave ferrite nonreciprocal device, be a kind of TD-SCDMA Surface Mount miniaturization circulator.
Background technology
The existing embedded circulator that is used for mobile communcations system, overall dimension is 3/4 inch structural member, the unique shortcoming of this structure is exactly that volume ratio is bigger, can only use single channel or two-way passage under the TD-SCDMA system, can not satisfy the requirement of TD-SCDMA system.
Summary of the invention
Problem to be solved in the utility model is: it is bigger to have the circulator volume that is used for mobile communcations system now, can not satisfy the user demand of miniaturization, particularly the user demand of TD-SCDMA system.
The technical solution of the utility model is: TD-SCDMA Surface Mount miniaturization circulator, comprise incorporate magnetic conduction cavity, barium iron permanent magnet, upside is spared magnetic sheet, downside is spared magnetic sheet, the upside ferrite, the downside ferrite, center conductor, the samarium cobalt permanent magnet body, temperature-compensating sheet and magnetic conduction cover plate, the temperature-compensating sheet, the samarium cobalt permanent magnet body, upside is spared magnetic sheet, the upside ferrite, center conductor, the downside ferrite, downside is spared magnetic sheet, barium iron permanent magnet from top to bottom stacks gradually and is arranged in the magnetic conduction cavity, magnetic conduction cavity and magnetic conduction cover plate constitute the cavity of sealing, wherein, upside ferrite and downside ferrite are fixed in the magnetic conduction cavity by two ceramic dielectric rings.
Three lead-in wires of the utility model center conductor are drawn the magnetic conduction cavity, and the output of lead-in wire is concordant with magnetic conduction cavity bottom surface; Center conductor adopts the beryllium-bronze of 0.13mm, and upside ferrite and downside ferrite are of a size of 10.5 * 0.9mm, and circulator is of a size of 1/2 inch; In order further to reduce the insertion loss of device, magnetic conduction cavity, center conductor, the even magnetic sheet of upside, the even magnetic sheet of downside and temperature-compensating sheet electroplate.
The purpose of this utility model is to overcome the weak point that exists on the existing built-in small circulator volume and provides a kind of volume little, 1/2 inch circulator of Embedded Surface Mount, Embedded structure has been saved installing component, save the space, dielectric ring can improve miniaturization circulator installation accuracy when mounted, simultaneously in the selection of permanent magnet, samarium cobalt permanent magnet body coercive force height, saturation magnetic field intensity height, a little less than the magnetic field intensity of barium iron permanent magnet, regulate than being easier to, in product was realized, the barium iron permanent magnet combination of using the samarium cobalt permanent magnet body of small size and being easy to debug can realize good performance under to the restriction of components and parts volume at small-sized circulator; Under the structure situation of the system's same size that uses circulator, the volume of circulator is more little, just can increase passage, uses after the utility model Surface Mount miniaturization circulator, and the TD-SCDMA system can make four paths into by original single channel or two-way.
Embedded Surface Mount miniaturization circulator overall dimension of the present utility model can narrow down to 1/2 inch, simultaneously because adopted that cavity is integrated, ferrite measures such as two-sided magnetization and device surface be silver-plated up and down, it is good to have the magnetic circuit closure, characteristics such as leakage field is little, magnetic conduction cavity and magnetic conduction cover plate compress by screw thread, and need not adhesive and screw can assemble, the reliability height, the device overall performance is good, can be widely used in microwave communication particularly in the 3G communication system.
