2A3/2A3A
0.3 Watts, 20 Volts, Class A
Linear to 2000 MHz
GENERAL DESCRIPTION
The 2A3 is a COMMON EMITTER transistor capable of providing up to
0.3 Watt of Class A, RF output power to 2000 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.
