QPL8831 75 17dB CATV Amplifier (51218MHz) ))) Product Overview The QPL8831 is an ultra-linear GaAs pHEMT 75-Ohm RF balanced amplifier IC with 51218 MHz operating bandwidth, featuring high linearity, high gain and low noise for use as a post amplifier in optical receivers or as a low noise balanced preamp. This IC uses a 5V supply for applications requiring lower power dissipation. Due to its wide operational bandwidth the QPL8831 can also be used as a downstream amp in 8-Pin SOIC Package DOCSIS 3.1 as well as an upstream amplifier for DOCSIS 3.1 or DOCSIS 4.0 applications.
