The QPL9098 is an ultra-low noise gain block amplifier that operates from 4 to 6 GHz. At 5.5 GHz, the amplifier provides a gain of 19 dB, OIP3 of 32 dBm and a noise figure of 1.3 dB while drawing 68 mA current from a 4.2 V supply. The LNA integrates a bypass path and is internally matched to 50 ohms. It requires only four external components for operation from a single positive supply: an external RF choke and blocking/bypass capacitors. The QPL9098 is available in a 2 x 2 mm DFN package and is ideal for TDD or FDD systems, repeaters, base-station receivers and tower mount amplifier applications. This amplifier uses a high performance E-pHEMT process.
