GENERAL DESCRIPTION
The 0405-500L is an internally matched, COMMON EMITTER transistor
capable of providing 500 Watts of pulsed RF output power in a push-pull
configuration at one thousand and one hundred microsecond pulse width
twenty –six percent duty factor across the frequency band 400-450 MHz. This
hermetically sealed tran sistor is specifically design ed for medium pulse radar
applications. It utilizes gold metallization and diffused emitter ballasting to
provide high reliability and supreme ruggedness.
