- SOT-89 Package
The QPL1812 is a high performance pHEMT MMIC amplifier designed to run from a single 8 V supply, without the need for an external dropping resistor. The high gain, high linearity, and low distortion from 50 MHz to 1800 MHz make this part ideal for broad-band cable applications. An integrated active bias circuit provides stable gain over temperature and process variations. It is offered in a small SOT-89 package and is RoHS compliant.
Typical Applications
- DOCSIS 4.0
- Head End CMTS Equipment
- CATV Optical Nodes and Amplifiers
- Cable Modem and Set Top Box
