UDR-500
500 Watts - 40 Volts, Pulsed
Radar 400 - 450 MHz
GENERAL DESCRIPTION
The UDR-500 is an internally matched, COMMON EMITTER transistor
capable of providing 500 Watts of pulsed RF output power at sixty
microseconds pulse width, two percent duty factor across the band 400-450
MHz. This hermetically solder sealed transistor is specifically designed for
long pulse radar applications. It utilizes gold metalization and diffused emitter
ballasting to provide high reliability and supreme ruggedness.
