MRF177
100 W, 28 V, 400 MHz N-CHANNEL BROADBAND RF POWER MOSFET
N-Channel Enhancement Mode MOSFET
Designed for broadband commercial and military applications up to 400 MHz frequency range. Primarily used as a driver or output amplifier in push-pull configurations. Can be used in manual gain control, ALC and modulation circuits. * Typical Performance at 400 MHz, 28 V: Output Power -- 100 W Gain -- 12 dB Efficiency -- 60% * Low Thermal Resistance * Low Crss -- 10 pF Typ @ VDS = 28 Volts * Ruggedness Tested at Rated Output Power * Nitride Passivated Die for Enhanced Reliability * Excellent Thermal Stability; Suited for Class A Operation
