    The QPB7425 is a GaAs pHEMT single ended RF amplifier IC featuring 25 dB of flat gain and low noise. This IC is designed to support Fiber to The Home (FTTH) applications from 47 to 1218 MHz using a single 8 V supply. 5 V operation is possible in applications with reduced linearity and gain requirements. QPB7425 offers low noise and distortion plus high gain in a SOT-89 package for convenient layout and design in set top and infrastructure projects for 75 Ω CATV and satellite applications.
