1618-35
35 Watt - 28 Volts, Class C
Microwave 1600 - 1800 MHz
GENERAL DESCRIPTION
The 1618-35 is a COMMON BASE transistor capable of providing 35 Watts
of Class C, RF output power over the band 1600-1800 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.
