Ultra-linear PA/Driver
Tuning Range: 0.1 – 3.8 GHz

GRF4107 is a high linearity PA /Linear Driver with high reverse isolation. It delivers excellent Gain, P1dB and IP3 over a wide range of frequencies with fractional bandwidths of roughly 5 to 10%.

The device is primarily targeted at applications below 2.7 GHz but can be used up to 3.8 GHz with a suitable driver amplifier. It can be biased over a wide range of Vcc from 3.0 to 5.0 volts and ICCQ is adjustable for optimal efficiency and linearity.
