Abstract
The utility model proposes tilting Contiuum type dielectric filter, including medium body, the medium body includes front end face and rear end face disposed in parallel, upper and lower surface disposed in parallel and left side disposed in parallel and right side；Run through on the front end face and the rear end face and offer several tuning through-holes, wherein the angle of the left side and the front end face is acute angle.The filter of existing rectangular-shape by being changed into the filter of tilting by the utility model so that filter becomes smaller on the width, meets the needs of client is to " thin " product, while adapting to the trend of product miniaturization.
Description
Technical field
The utility model is related to filter fields, more particularly, to a kind of tilting Contiuum type dielectric filter.
Background technology
With the fast development of wireless communication technique, electronics industry bound pair is also higher and higher in electronics miniaturization requirement,
Radio communication product develops towards the directions such as short, small, light, thin；Filter is as device important in wireless telecommunications, miniaturization
Demand it is increasing, wherein in order to adapt to demand of the client for " thin ", that is, require us to make existing filter and change
Into.
Invention content
The utility model proposes a kind of dielectric filters of improved Contiuum type, change existing filter appearance, with full
