QPB7425 75 25dB CATV Amplifier (47 1218MHz) Product Overview The QPB7425 is a GaAs pHEMT single ended RF amplifier IC featuring 25dB of flat gain and low noise. This IC is designed to support Fiber to The Home (FTTH) applications from 47 to 1218MHz using a single 8V supply. Operation down to 3V is possible for applications with reduced linearity requirements. QPB7425 offers extremely low noise and distortion plus high gain in a SOT-89 package for convenient layout and design in set top and infrastructure projects SOT-89 Package for 75 CATV and satellite applications.
