Product Details

The ADCA3992 is a high gain, power doubler hybrid amplifier optimized for a wide range of bias conditions for power efficiency and customer flexibility. The ADCA3992 is ideally suited for use in digital predistortion (DPD) node designs for maximum power savings. The device achieves extremely high RF output, up to 76.8 dBmV composite power, or 67 dBmV virtual level, using a gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) die in combination with a gallium nitride (GaN) HEMT die. The dc current and supply voltage can be adjusted externally for optimum distortion performance vs. power consumption over a range of output levels. The ADCA3992 is packaged in the industry-standard SOT115J package.

Applications

  • 45 MHz to 1218 MHz cable television (CATV) infrastructure amplifier systems
  • Remote physical layer (PHY) and fiber deep nodes
  • DOCSIS® 3.1 compliant
