The QPL1842 is a GaAs pHEMT single ended MMIC RF amplifier IC featuring 25dB of gain and low noise from 5MHz to 850MHz. This high linearity 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 combination of low noise, excellent distortion, and low gain make this suitable for drop amps and other distribution amps. The device is powered by a single supply that can operate from 5V to 8V with current set from 250-375mA. At 5V, the QPL1842 provides an output of 64.5dBmV TCP with a CCN of 51dB. The device is packaged in a 12-pin 5x5mm² Laminate Module.
Typical Applications
- DOCSIS 4.0 Amplifiers
- DOCIS 4.0 Nodes
- DOSCIS 4.0 Remote PHY Devices
- DOSCSIS 4.0 Cable Modems and Home Gateways
