2729 – 120
120 Watts - 36 Volts, 100µs, 10%
Radar 2700-2900 MHz
PRELIMINARY
GENERAL DESCRIPTION
The 2729-120 is an internally matched, COMMON BASE transistor
capable of providing 120 Watts of pulsed RF output power at one
hundred microseconds pulse width, ten percent duty factor across the
band 2700 to 2900 MHz. This hermetically solder-sealed transistor is
specifically designed for S-Band radar applications. It utilizes gold
metalization and emitter ballasting to provide high reliability and
supreme ruggedness.
