The 0405-1000M is an internally matched, COMMON EMITTER transistor capable of providing 1000 Watts of pulsed RF output power in a push-pull configuration at three hundreds microsecond pulse width ten percent duty factor across the frequency band 400-450 MHz. This hermetically sealed transistor is specifically designed for medium pulse radar applications. It utilizes gold metallization and diffused emitter ballasting to provide high reliability and supreme ruggedness.
