Spread Spectrum Solid State Linear Amplifier , Rf Driver Amplifier YP552228

TXtelsig YP552228 Wifi RF Amplifier

The YP552228 is a 2-stage 4.9-5.9GHz high efficiency, high linearity power amplifier based on InGaP/GaAs HBT technology. The amplifier provides a typical gain of 22 dB and P1dB power of 30.5 dBm, typical bias condition is 5.5V at 240 mA. The input and output are internally matched to 50Ω and require a minimum of external matching components to cover the entire 4.9GHz to 5.9GHz. The YP552228 is assembled in a 16-pin, 4mm×4mm, QFN package.
