1214-32L
32 Watts, 36 Volts
Pulsed Radar at 1.2-1.4 GHz
GENERAL DESCRIPTION
The 1214 -32L is an internally matched, COMMON BASE transistor capable of
providing 32 Watts of pulsed RF output power at 5 milliseconds pulse width,
20% 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.
