RF Power

Field Effect Transistor

N–Channel Enhancement Mode MOSFET

Designed for broadband commercial and military applications up to 200 MHz

frequency range. The high–power, high–gain and broadband performance of

this device make possible solid state transmitters for FM broadcast or TV

channel frequency bands.

• Guaranteed Performance at 150 MHz, 28 V:

Output Power = 80 W

Gain = 11 dB (13 dB Typ)

Efficiency = 55% Min. (60% Typ)

• Low Thermal Resistance

• Ruggedness Tested at Rated Output Power

• Nitride Passivated Die for Enhanced Reliability

• Low Noise Figure — 1.5 dB Typ at 2.0 A, 150 MHz

• Excellent Thermal Stability; Suited for Class A Operation
