GENERAL DESCRIPTION
The 1719-35 is a COMMON BASE transistor capable of providing 35 Watts
of Class C, RF output power over the band 1725 -1850 MHz. This transistor is
designed for Microwave Broadband Class C, HIGH EFFICIENCY 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 Low Inductance Flange Mount, Ceramic
sealed package.
