The ARF466A and ARF466B comprise a symmetric pair of common source RF power transistors designed for pushpull scientific, commercial, medical and industrial RF power amplifier applications up to 45 MHz. They have been
optimized for both linear and high efficiency classes of operation.
• Low Cost Common Source RF Package.
• Low Vth thermal coefficient.
• Low Thermal Resistance.
• Optimized SOA for Superior Ruggedness.
• Specified 150 Volt, 40.68 MHz Characteristics:
•
Output Power = 300 Watts.
•
Gain = 16dB (Class AB)
•
Efficiency = 75% (Class C)
All Ratings: TC = 25°C unless otherwise specified.
