QPL1827
50 - 1800 MHz, 75 Ohm, 30 dB Gain CATV Amplifier
The QPL1827 is an ultra-linear, GaAs pHEMT, differential RF amplifier. The device features a 2-stage cascode design which provides 30dB of 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 dual supply that operates the first stage at 5V, and the second stage from 5V to 8V. The current can be set from 100mA to 165mA on the first stage, and 260mA to 350mA on the second stage. When the second stage is driven with 8V and 350mA the output is 67.5dBmV TCP with a CCN of 51dB. The QPL1827 is packaged in a 12-pin 5x5 mm2 Laminate Module.
