4CW100-000E Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – RF amplifier

4CW100,000E
The 4CW100,000E is ideal for use as a Class C RF
amplifier or oscillator, a Class AB RF linear amplifi-
er, or a Class AB push-pull AF amplifier or modula-
tor as well as a plate and screen-modulated Class
C RF amplifier. In a pulse modulator service, it can
deliver a peak output of 4 megawatts. The tube is
characterized by low input and feedback capaci-
tances and low internal lead inductances.
