Measuring the Capacitance Coefficients of Coaxial Open-circuits with Traceability to National Standards

Coaxial open-circuits are often used as measurement reference standards and can be found in most commercially available vector network analyzer (VNA) calibration kits. The capacitance characteristics of these devices are usually summarized in terms of ...

Coaxial open-circuit standards are found in many of today’s commercially available vector network analyzer (VNA) calibration kits. 1,2 They are most commonly used as standards in calibration schemes such as short-open-load-through (SOLT). In this capacity, they are assumed to have known characteristics, that is, they are assumed to provide...

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...
