Test Equipment

Pulser Heads for HBTs
AMCAD Engineering has released a new pulser, also referred to as probe head, tailored for small-periphery transistor (HBTs and HEMT) pulsed IV measurements. This new pulser, AM223, has two embedded measurement units: one for currents lower than 20 mA, one for currents between 20 and 200 mA. The system consists of two independently operating power modes – pulsed or DC (continuous mode). The maximum average power delivered by the sensors output is 50 W in pulsed mode, or 80 W in DC mode. This specification is linked to the external power probes used. The voltage measurements on the two channels are carried out from the internal resistance of each channel. The current measurements are made using differential measurements at the terminals of the same internal resistance.

Phase Stable Cables
Test grade cables are a must for RF applications. The test cables serve as the extension of the equipments' test ports. They provide flexibility for measuring cable assemblies or other microwave devices. It is vital to system performance that they remain stable when subjected to environmental or mechanical stresses. Phase stable cables have triple shielding with low loss dielectric and high temperature jacketing to minimize the phase effects when flexed multiple times. The connectors are made of rugged stainless steel for extended attachment and feature a strain relief support designed for armoring as an option. RF Precision Products now offers such cables for applications up to 26.5 GHz. Test charts are included. Off the shelf lengths are 24", 36" and 48". Custom lengths are available.
