An Educational Antenna Measurement System ORBIT/FR Horsham, PA The AL-2000-EDC Educational Antenna Measurement System is a low cost, yet versatile, automated antenna measurement system that allows a variety of antenna measurements to be accomplished in a small facility for a variety of antennas. The system is configurable for all...

Analog and Digital Signal Generators with High Spectral Purity Hewlett-Packard Co. Santa Rosa, CA Due to the increasingly stringent requirements for communications channels, today's signal generators must have extremely low phase noise to determine if a device, component or subsystem meets test specifications. A new series of spectrally pure...

A 165 W LDMOS FET for 900 MHz Operation An internally matched, common source, N-channel, enhancement-mode laterally diffused metal-oxide semiconductor (LDMOS) FET intended for large-signal amplifier applications in the 860 to 900 MHz frequency range has been developed. The model PTF 10100 LDMOS FET is rated at 165 W...
