SEMICONDUCTOR TECHNICAL DATA
The RF MOSFET Line
N–Channel Enhancement–Mode Lateral MOSFETs
Designed for broadband commercial and industrial applications with frequencies from 470 to 860 MHz. The high gain and broadband performance of these
devices make them ideal for large–signal, common source amplifier applications in 28/32 volt transmitter equipment.
• Typical CW Performance at 860 MHz, 32 Volts, Narrowband Fixture
Output Power — 75 Watts
Power Gain — 18.2 dB
Efficiency — 60%
• 100% Tested for Load Mismatch Stress at All Phase Angles
with 10:1 VSWR @ 32 Vdc, 860 MHz, 75 Watts CW
• Integrated ESD Protection
• Excellent Thermal Stability
• Characterized with Series Equivalent Large–Signal
Impedance Parameters
• In Tape and Reel. R1 = 500 units per 32 mm, 13 inch Reel.
