QPL9503 Overview
The QPL9503 is a flat-gain, high-linearity, ultra-low noise amplifier in a small 2 x 2 mm surface-mount package. The LNA provides a gain flatness of 2 dB (peak-to-peak) over a wide bandwidth from 3 to 6 GHz. At 5.5 GHz, the amplifier typically provides 21.6 dB gain, +35.5 dBm OIP3 at a 56mA bias setting, and 0.95 dB noise figure.
