8930 Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – RF Linear Amplifier

8930
The 8930 is electrically identical to the
4CX250R/7580W but the larger anode radiator as-
sembly allows higher dissipation with low air flow
and pressure drop characteristics. The tube has
rugged internal construction features for reliable
operation under heavy shock or vibration condi-
tions.
