Analog Devices ADCA3992 CATV Power Doubler Hybrid is optimised for a wide range of bias conditions for power efficiency and flexibility. The device is ideal for digital pre-distortion (DPD) node designs to maximise power savings.
The device achieves extremely high RF output, up to 76.8dBmV composite power, or 67dBmV virtual level. The device uses a GaAs, pHEMT die in combination with a GaN HEMT die. The DC current and supply voltage can be modified externally for optimum distortion performance vs power consumption over a variety of output levels. The device is packaged in the industry-standard SOT115J package.
Typical applications include 45MHz to 1218MHz CATV infrastructure amplifier systems, and remote physical layer and fibre deep nodes. The device is DOCSIS 3.1 compliant.
