1718-32L
32 Watt - 24 Volts, Class C
Microwave 1750 - 1850 MHz
GENERAL DESCRIPTION
The 1718-32L is a COMMON BASE transistor capable of providing 32
Watts of Class C, RF output power over the band 1750-1850 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.
