Product Specication
VHF push-pull power MOS transistor
BLF278
Class-AB operation
RF performance in CW operation in a common source push-pull test circuit. Th =25 °C; Rth mb-h = 0.15 K/W unless
otherwise specied. RGS = 2.8 per section; optimum load impedance per section = 0.74 + j2 ; (VDS = 50 V).
Ruggedness in class-AB operation
The BLF278 is capable of withstanding a load mismatch corresponding to VSWR =7:1 through all phases under the
conditions: VDS = 50 V; f = 225 MHz at rated output power.
