4CW50-000E Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – RF amplifier

4CW50,000E
The 4CW50,000E is characterized by low input
and feedback capacitances and low internal lead
inductances. A rugged mesh thoriated tungsten
filament provides adequate emission over the
long operating life. It is recommended for use as
a Class C RF amplifier or oscillator, a Class AB RF
linear amplifier, or a Class AB push-pull AF ampli-
fier or modulator. The 4CW50,000E is also use-
ful as a plate and screen-modulated Class C RF
amplifier.
