10AM20
20 Watts, 20 Volts, Class A
Linear to 1000 MHz
GENERAL DESCRIPTION
The 10AM20 is a COMMON EMITTER transistor capable of providing 20
Watts of Class A, RF output power to 1000 MHz. This transistor is
specifically designed for general Class A amplifier applications. It utilizes
gold metalization and diffused ballasting to provide high reliability and
supreme ruggedness. The transistor uses a fully hermetic High Temperature
Solder Sealed package.
