The QPL1822 is an ultra-linear, GaAs pHEMT, differential RF amplifier. The device features a cascode design which provides 15 dB of flat gain along with very low distortion from 50 MHz to 1.8 GHz. This ultra-linear IC is designed to support Broadband CATV DOCSIS 4.0 applications, such as Nodes, Amplifiers, and Remote PHY Devices, as well as Fiber to The Home (FTTH), Home Gateways, and Cable Modems. The device is powered by a single 5 V supply at 260 mA which provides an output of 63 dBmV TCP at an MER of 45 dB. The QPL1822 is packaged in a 12-pin 5×5 mm2 Laminate Module.
