Freescale Semiconductor

RF Power Field Effect Transistors

N-Channel Enhancement-Mode Lateral MOSFETs

Designed for broadband commercial and industrial applications with frequen-

cies up to 1000 MHz. The high gain and broadband performance of these

devices make them ideal for large-signal, common-source amplifier applica-

tions in 28 volt base station equipment.

• Typical Two-Tone Performance at 945 MHz, 28 Volts

Output Power — 45 Watts PEP

Power Gain — 18.8 dB

Efficiency — 42%

IMD — -32 dBc

• Capable of Handling 10:1 VSWR, @ 28 Vdc, 945 MHz, 45 Watts CW

Output Power
