250 Watts, 40 Volts, 200
s, 10%
Radar 1480 to 1650 MHz
GENERAL DESCRIPTION
The 1517-250M is an internally matched, COMMON BASE transistor capable
of providing 250 Watts of pulsed RF output power at 200 microseconds pulse
width, 10% duty factor across the band 1480 to 1650 MHz. This hermetically
solder-sealed transistor is specifically designed for upper L-Band radar
applications. It utilizes gold metallization and diffused emitter ballasting to
provide high reliability and supreme ruggedness.
