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

• Integrated ESD Protection

• Designed for Maximum Gain and Insertion Phase Flatness

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

Output Power

• Excellent Thermal Stability

• Characterized with Series Equivalent Large−Signal Impedance Parameters

• In Tape and Reel. R1 Suffix = 500 Units per 32 mm, 13 inch Reel.

• Low Gold Plating Thickness on Leads. L Suffix Indicates 40µ″ Nominal.
