The ARF473 is a matched pair of RF power transistors in a common source configuration. It is designed for high voltage
push-pull or parallel operation in narrow band ISM and MRI power amplifiers up to 150 MHz.
⢠Specified 135 Volt, 130 MHz Characteristics:
⢠High Performance Push-Pull RF Package.
â¢
Output Power = 300 Watts.
⢠High Voltage Breakdown and Large SOA
â¢
Gain = 13dB (Class AB)
â¢
Efficiency = 50%
for Superior Ruggedness.
⢠Low Thermal Resistance.
MAXIMUM RATINGS
All Ratings: TC = 25°C unless otherwise specified.
