2225-4L
3.5 Watts, 24 Volts, Class C
Microwave 2200-2500 MHz
GENERAL DESCRIPTION
The 2225-4L is a COMMON BASE transistor capable of providing 3.5 Watts,
Class C output power over the band 2200-2500 MHz. The transistor includes
input 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.
