2A8
0.5 Watts, 20 Volts, Class A
Linear to 2000 MHz
GENERAL DESCRIPTION
The 2A8 is a COMMON EMITTER transistor capable of providing 0.5 Watts
of Class A, RF output power at 2000 MHz. This transistor is specifically
designed for general Class A amplifier applicatons. It utilizes gold
metalization and diffused ballasting to provide high reliability and supreme
ruggedness.
