N–Channel Enhancement–Mode Lateral MOSFET
Designed for broadband commercial and industrial applications with frequencies from 470 to 860 MHz. The high gain and broadband performance of this
device make it ideal for large–signal, common source amplifier applications in
28/32 volt transmitter equipment.
• Typical Two–Tone Performance @ 860 MHz, 32 Volts, Narrowband Fixture
Output Power — 130 Watts PEP
Power Gain — 17.3 dB
Efficiency — 41%
IMD — –32.5 dBc
• 100% Tested for Load Mismatch Stress at All Phase Angles with 10:1
VSWR @ 32 Vdc, 860 MHz, 130 Watts, f1 = 857 MHz, f2 = 863 MHz
• Integrated ESD Protection
• Excellent Thermal Stability
• Characterized with Differential Large–Signal Impedance Parameters
470 – 860 MHz, 130 W, 32 V
