Overview
RF POWER MOSFETs N - CHANNEL ENHANCEMENT MODE ARF461A(G) TO-247 ARF461B(G) Common Source 250V 150W 65MHz The ARF461A and ARF461B comprise a symmetric pair of common drain 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 250 Volt, 40.
68 MHz Characteristics: • Output Power = 150 Watts.
• Gain = 13dB (Class AB) • Efficiency = 75% (Class C) • Low Cost Common Source RF Package.
• Low Vth thermal coefficient.
• Low Thermal Resistance.
• Optimized SOA for Superior Ruggedness.
