N-CH ANNEL ENHANCEMENT MODE 65V 150W 65MHz

The ARF462A and ARF462B comprise a symmetric pair of common source RF power transistors designed for push­pull scientific, commercial, medical and industrial RF power amplifier applications up to 65 MHz. They have been
optimized for both linear and high efficiency classes of operation.

• Specified 65 Volt, 40.68 MHz Characteristics:

• Output Power = 150 Watts.

• Gain = 15dB (Class AB)

• Efficiency = 75% (Class C)

MAXIMUM RATINGS All Ratings: TC = 25°C unless otherwise specified.

Symbol

Parameter

• Low Cost Common Source RF Package.

• Low Vth thermal coefficient.
