Radar 1200 - 1400 MHz
GENERAL DESCRIPTION
CASE OUTLINE
The 1214-30 is an internally matched, COMMON BASE transistor capable of
providing 30 Watts of pulsed RF output power at two milliseconds pulse
width, twenty percent duty factor across the band 1200 to 1400 MHz. This
hermetically solder-sealed transistor is specifically designed for long pulse
radar applications. It utilizes gold metalization and diffused emitter ballasting
to provide high reliability and supreme ruggedness.
