2729-125
125 Watts, 36 Volts, 100s, 10%
Radar 2700-2900 MHz
GENERAL DESCRIPTION
The 2729-125 is an internally matched, COMMON BASE bipolar transistor
capable of providing 125 Watts of pulsed RF output power at 100s pulse
width, 10% duty factor across the 2700 to 2900 MHz band. The transistor
prematch and test fixture has been optimized through the use of Pulsed
Automated Load Pull. This hermetically solder-sealed transistor is specifically
designed for S-band radar applications. It utilizes gold metallization and emitter
ballasting to provide high reliability and supreme ruggedness.
