55 Watts - 28 Volts, Pulsed
Radar 1200 - 1400 MHz
GENERAL DESCRIPTION
The 1214-55 is an internally matched, COMMON BASE transistor capable
of providing 55 Watts of pulsed RF output power at two milliseconds pulse
width, twenty percent duty factor across the band 1200 to 1400 MHz. This
hermetically solder-sealed transistor is specifically designed for L-Band radar
applications. It utilizes gold metalization and diffused emitter ballasting to
provide high reliability and supreme ruggedness.
