Metal-clad Fibers with Significant Weight Savings and EMI Performance

Micro-Coax, Pottstown, PA

Micro-Coax is now offering the ARACON“ family of metal-clad fibers that combines the conductivity of metal with the strength, light weight and flexibility of Kevlar® aramid fibers. The ARACON fibers are a superior lightweight alternative to traditional nickel-plated copper wire for EMI shielding. Replacing standard wire with ARACON offers significant weight savings without sacrificing EMI performance, as well as other benefits that copper and alloy wires cannot match.

Design of Bias Tees for a Pulsed-bias, Pulsed-RF Test System Using Accurate Component Models

In this article, a design of custom bias tees to be used in a pulsed-bias, pulsed-RF measurement system is described. The bias tee design is such that the DC path allows bias pulses to pass through to the device unchanged, while still allowing RF measu...
This article describes the design of a bias tee for a pulsed-bias, pulsed-RF test system. The cut-off frequency of the DC path was raised to allow pulsing of the bias signal. The theory of bias tee design for pulsed measurements is first presented. The simulation results for the design...

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,...
