ARF300

ARF300 125V, 300W, 45MHz N-CHANNEL ENHANCEMENT MODE The ARF300 is a N-CHANNEL RF power transistor in a high efficiency flangeless package. It is designed for high voltage operation in narrow band ISM and MRI power amplifiers at frequencies up to 45MHz. The transistor is well matched to the ARF301 P-CHANNEL RF power transistor making the pair well suited for bridge configurations RF POWER MOSFET • Specified 125 Volt, 27 MHz Characteristics: Output Power = 300 Watts. Gain = 15dB (Class E) Efficiency = 80% • RoHS Compliant • High Performance • High Voltage Breakdown and Large SOA for Superior Ruggedness • Low Thermal Resistance. • Capacitance matched with ARF301 P-Channel Maximum Ratings Symbol VDSS VDGO ID VGS PD TJ, TSTG TL Parameter Drain-Source Voltage Drain-Gate Voltage Continuous Drain Current @ TC = 25°C Gate-Source Voltage Total Power Dissipation @ TC = 25°C Operating and Storage Junction Temperature Range Lead Temperature: 0.063” from Case for 10 Sec.
