1214 - 300

300 Watts - 50 Volts, 100µs, 10%

Radar 1200 - 1400 MHz

GENERAL DESCRIPTION

The 1214-300 is an internally matched, COMMON BASE transistor capable
of providing 300 Watts of pulsed RF output power at one hundred
microseconds pulse width, ten 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.
