Test fixture and test method of dielectric waveguide filter

Abstract

The invention discloses a test fixture and a test method of a dielectric waveguide filter. The test fixture of the dielectric waveguide filter directly uses an SMA (Small A Type) connector to be connected with the dielectric waveguide filter, the connection of the test fixture and the dielectric waveguide filter is realized without the devices such as an adapter, the concrete structure of the testfixture of the dielectric waveguide filter is simplified, and the connected relation between the dielectric waveguide filter and the test fixture of the dielectric waveguide filter is simplified, sothat the test process of the dielectric waveguide filter by using the test fixture of the dielectric waveguide filter is simplified. Moreover, the test fixture of the dielectric waveguide filter alsohas the function of a clamping device for realizing clamping fixation of the dielectric waveguide filter, and the uniformity and stability of the test fixture of the dielectric waveguide filter for the test of the dielectric waveguide filter are improved.

Description

technical field [0001] The present application relates to the technical field of equipment testing devices, and more specifically, to a testing fixture for a dielectric waveguide filter and a testing method thereof. Background technique [0002] Dielectric waveguide filters are filters made of high dielectric constant ceramic materials, which have many advantages such as small size, low loss, small frequency temperature coefficient and thermal expansion coefficient, and high Q value. [0003] When testing dielectric waveguide filters, it is necessary to design special test fixtures. In the prior art, the test fixtures for dielectric waveguide filters usually use adapters, SMP connectors ("board-to-board" coaxial connectors) and test boards. The pattern realizes the structural design of the test fixture, but the structure of the test fixture in this mode is relatively complicated, and the connection relationship between the dielectric waveguide filter and the test fixture is ...
