GENERAL DESCRIPTION
The 1214-370M is an internally matched, COMMON BASE transistor
capable of providing 370 Watts of pulsed RF output power at 330
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 metallization and diffused
emitter ballasting to provide high reliability and supreme ruggedness.
