ARF300

125V, 300W, 45MHz

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

• High Performance

• High Voltage Breakdown and Large SOA

for Superior Ruggedness

• Low Thermal Resistance.

• Capacitance matched with ARF301 P-Channel
