0405-500L

0405-500L Rev A . 0405-500L 500 Watts - 32Volts, 1100µs, 26% UHF Pulsed Radar 400 - 450 MHz 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 transistor is specifically designed for medium pulse radar applications. It utilizes gold metallization and diffused emitter ballasting to provide high reliability and supreme ruggedness.
