The ARF461C and ARF461D comprise a symmetric pair of common drain RF power transistors designed for push-
pull scientic, commercial, medical and industrial RF power amplier applications up to 65 MHz. They have been
optimized for both linear and high efciency classes of operation.
Specied 250 Volt, 40.68 MHz Characteristics:
Output Power = 150 Watts.
Gain = 13dB (Class AB)
Efciency = 75% (Class C)
Low Cost Common Source RF Package.
Low Vth thermal coefcient.
Low Thermal Resistance.
Optimized SOA for Superior Ruggedness.
