N-CH ANNEL ENHANCEMENT MODE 125V 100W 100MHz

The ARF463A and ARF463B comprise a symmetric pair of common source RF power transistors designed for push­pull scientific, commercial, medical and industrial RF power amplifier applications up to 100 MHz. They have been
optimized for both linear and high efficiency classes of operation.

• Specified 125 Volt, 81.36 MHz Characteristics:

• Output Power = 100 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.
