Product specification

VHF linear power transistor

BLV33F

RF performance in VHF class-AB operation (C.W.).

Note

1. Gain compression point of 1 dB is at typical 85 W (minimum 75 W). Using a 3rd-order amplitude transfer

characteristic, 1 dB compression corresponds with 30 % sync input / 25 % sync output compression in television

service (negative modulation, C.C.I.R. system).
