The GRF5110 is a low noise amplifier/driver that can be tuned from 1.5 to 3.8 GHz. The amplifier can cover fractional bandwidths of roughly 5 to 10 percent. At 1.9 GHz, it provides a gain of 15 dB with a noise figure of 0.9 dB. The LNA delivers a P1dB of 28.8 dBm, OIP3 of 46 dBm while operating at 5.0 volts and consuming 150 mA of current. It is available in an ultra-small surface mount package and is ideal for power amplifier drivers, multi-stage LNA's and linear drivers for high PAR waveform applications.
