QPL1820 75 22dB CATV Amplifier (50 1800MHz) Product Overview The QPL1820 is an ultra-linear, GaAs pHEMT, differential RF amplifier. The device features a cascode design which provides 22dB of flat gain along with very low distortion from 50MHz to 1.8GHz. 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 supply that can operate from 5V to 8V and current can be set from 260 mA to 350 mA. At 5V and 260 mA the QPL1820 provides an output of 63dBmV TCP with a MER of 45dB. When driven with 8V and 350mA the output is 67 dBmV TCP with a MER 2 of 45dB. The QPL1820 is packaged in a 12-pin 5x5 mm Laminate Module.
