SEMICONDUCTOR TECHNICAL DATA
The RF MOSFET Line
N–Channel Enhancement–Mode Lateral MOSFETs
Designed for broadband commercial and industrial applications at frequencies to 1.0 GHz. The high gain and broadband performance of these devices
makes them ideal for large–signal, common source amplifier applications in 28
volt base station equipment.
• Guaranteed Performance @ 945 MHz, 28 Volts
Output Power = 60 Watts
Power Gain = 11.5 dB
Efficiency = 53%
• Characterized with Series Equivalent Large–Signal
D
