MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
The RF MOSFET Line
Power Field Effect Transistor
N–Channel Enhancement–Mode MOSFET
Designed primarily for wideband large–signal output and driver stages to
500 MHz.
• Push–Pull Configuration Reduces Even Numbered Harmonics
• Typical Performance at 400 MHz, 28 Vdc
Output Power = 40 Watts
Gain = 13 dB
Efficiency = 50%
• Typical Performance at 175 MHz, 28 Vdc
Output Power = 40 Watts
Gain = 17 dB
Efficiency = 60%
• Excellent Thermal Stability, Ideally Suited for Class A Operation
• Facilitates Manual Gain Control, ALC and Modulation Techniques
• 100% Tested for Load Mismatch at All Phase Angles with 30:1 VSWR
• Low Crss — 4.5 pF @ VDS = 28 Volts
• Circuit board photomaster available upon request by
contacting RF Tactical Marketing in Phoenix, AZ.
