Lightweight 0.190" spaceflight microwave cable assemblies have been introduced that weigh 20 percent less than the company's traditional 0.190" cable assemblies. The new cables are qualified to operate up to 18 GHz over a -100° to +125°C temperature range and are designed to meet the rigorous requirements of the...Read More
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...Read More
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.
