2 Watt - 28 Volts, Class C  
Microwave 1700 - 2000 MHz  
GENERAL DESCRIPTION  
CASE OUTLINE  
The 1720-2 is a COMMON BASE transistor capable of providing 2 Watts of  
Class C, RF output power over the band 1700-2000 MHz. This transistor is  
designed for Microwave Broadband Class C amplifier applications. It includes  
Input prematching and utilizes Gold metalization and diffused ballasting to  
provide high reliagility and supreme ruggedness.
