Abstract

Disclosed are a detecting clamp and device of microwave ceramic component and a method for detecting. The clamp comprises a microwave coplane waveguide, a sample position chip, detecting probe mount and a SMA adaptor. The microwave ceramic component detecting device comprises a microwave network analyzer, a microwave coplane waveguide testing clamp, input coaxial cables and output coaxial cables. The detecting method comprises steps of: taking open circuit and short circuit calibrating detection and match load calibration, then measuring data, and taking parallel and serial detection on the components for detecting, finally entering testing software for data analysis, calculation, process and storage.

Description

technical field [0001] The present invention relates to a component detection device, in particular to a radio frequency and microwave ceramic components (including resonators, filters, duplexers, capacitors and inductors, etc.) A fixture and device for multi-parameter non-destructive testing under different conditions and a testing method thereof. Background technique [0002] In recent years, with the development of millimeter wave and submillimeter wave technology, coplanar waveguide (CPW) has received attention (Zhou Xilang, Conformal Transformation Analysis of Modified Coplanar Waveguide [J], Journal of Communications, 1997, 18(11) : 65-70; Carlsson E. Confomalmapping of the field and charge distributions in multi-layered substrate CPW's[J].IEEE Trans, MTT, 1999, 47(8): 1544-1552), the reason is that compared with conventional micro For striplines, coplanar waveguides have outstanding advantages when used in GaAs monolithic microwave integrated circuits (GaAs sMMICs). ...
