SEMICONDUCTOR TECHNICAL DATA
The RF Line
NPN Silicon
RF Power Transistor
. . . designed primarily for wideband large–signal driver and predriver amplifier
stages in the 200–500 MHz frequency range.
• Guaranteed Performance at 400 MHz, 28 V
Output Power = 20 Watts
Power Gain = 10 dB Min
Efficiency = 50% Min
• 100% Tested for Load Mismatch at all Phase Angles with 30:1 VSWR
• Gold Metallization System for High Reliability
• Computer–Controlled Wirebonding Gives Consistent Input Impedance
