SEMICONDUCTOR TECHNICAL DATA
The RF Sub - Micron MOSFET Line
RF Power Field Effect Transistors
N - Channel Enhancement - Mode Lateral MOSFETs
frequencies from 865 to 895 MHz. The high gain and broadband performance
of these devices make them ideal for large - signal, common - source amplifier
applications in 26 volt base station equipment.
• Typical CDMA Performance @ 880 MHz, 26 Volts, I
• Internally Matched, Controlled Q, for Ease of Use
• High Gain, High Efficiency and High Linearity
• Integrated ESD Protection
• Designed for Maximum Gain and Insertion Phase Flatness
• Capable of Handling 10:1 VSWR, @ 26 Vdc, 880 MHz, 90 Watts CW
• Excellent Thermal Stability
• Characterized with Series Equivalent Large - Signal Impedance Parameters
• Low Gold Plating Thickness on Leads, 40µ″ Nominal.
• In Tape and Reel. R3 Suffix = 250 Units per 56 mm, 13 inch Reel.
