20 Watt - 28 Volts, Class C
Microwave 1700 - 1900 MHz
GENERAL DESCRIPTION
The 1719-20 is a COMMON BASE transistor capable of providing 20 Watts
of Class C, RF output power over the band 1700-1900 MHz. This transistor is
designed for Microwave Broadband Class C amplifier applications. It includes
Input and Output prematching and utilizes Gold metalization and diffused
ballasting to provide high reliability and supreme ruggedness. The transistor
uses a fully hermetic High Temperature Solder sealed package.
