BLF202
APPLICATION INFORMATION FOR CLASS-B OPERATION
Tmb =25 °C; RGS = 237 ; unless otherwise specied.
RF performance in CW operation in a common source class-B test circuit.
Ruggedness in class-B operation
The BLF202 is capable of withstanding a load mismatch corresponding to VSWR = 50:1 through all phases under the
following conditions: VDS = 15.5 V; f = 175 MHz at rated load power.
