Design of a TRM Calibration Kit for the ZMA Coaxial Interface Using Ansoft HFSS

When new coaxial interfaces become available, it is important to validate their performance. The best way to do this is by using a calibration kit that eliminates the effects of adapters in the measurement. This article discusses the design and impleme...
One of the greatest challenges in characterizing new coaxial interfaces is to determine an accurate test configuration. When precision airlines are not available it is very difficult to obtain a true measurement of the device under test. It becomes necessary to design and implement calibration standards to eliminate the...

Fast and Accurate High Power Device Characterization with a Microstrip SOL Method

High power device characterizations, performed with a microstrip short-open-load (SOL) calibration kit, are presented. This article demonstrates an interesting alternative to the classical through-reflect-line (TRL) method, when only terminating impeda...
Precise device characterization is the starting point of any good circuit design. This task can be particularly challenging when the device is a high power transistor having low input and output impedances. For devices working only under pulse conditions, specific test benches exist 1 but are rather complicated and...

2003 Connector, Cable and Cable Assembly Survey

This is the first survey of connectors, cables and cable assemblies sponsored by Microwave Journal. We hope to update it annually with increased industry participation.
On December 13, 2002, we sent a questionnaire to 75 companies that provide products and services in this field, with a response deadline of January 11th. We used e-mail rather than the USPS so that we would have feedback that all the questionnaires were received. On January 3, 2003,...
