Qorvo QPL7420 CATV GaAs pHEMT RF Amplifier ICs

Qorvo QPL7420 CATV GaAs pHEMT RF Amplifier ICs are single-ended devices featuring 20dB flat gain and low noise for applications in the upstream from 5MHz to 684MHz and in the downstream from 47MHz to 1800MHz. Using a single 5V supply, the QPL7420 ICs can be used from 3V to 8V (depending on linearity requirements). The Qorvo QPL7420 CATV GaAs pHEMT RF Amplifier ICs offer low noise and distortion plus high gain in a 3mm² QFN package for a convenient layout and design in set-top and infrastructure projects for 75Ω CATV and satellite applications.
