25 Watts, 24 Volts, Class C
Microwave 2000 - 2130 MHz
GENERAL DESCRIPTION
The 2021-25 is a COMMON BASE transistor capable of providing 25 Watts,
Class C output power over the band 2000-2130 MHz. The transistor includes
input and output prematching for full Broadband capability. Gold
metalization and diffused ballasting are used to provide high reliability and
supreme ruggedness. The transistor uses a fully hermetic High Temperature
Solder Sealed package.
