VHF power MOS transistor
BLF346
APPLICATION INFORMATION
RF performance in a linear amplier (common source class-A circuit).
Rth mb-h = 0.2 K/W; ZL = 1.1 + j0.2 unless otherwise specied.
Note
1. Three-tone test method (vision carrier
8 dB, sound carrier 7 dB, sideband signal 16 dB), zero dB corresponds to
peak synchronization level.
Ruggedness in class-A operation
The BLF346 is capable of withstanding a load mismatch corresponding to VSWR = 50 : 1 through all phases under the
following conditions: VDS = 28 V; f = 225 MHz at rated output power.
