APPLICATIONS 45 MHz to 1218 MHz cable television (CATV) infrastructure amplifier systems Remote physical layer (PHY) and fiber deep nodes DOCSIS 3.1 compliant GENERAL DESCRIPTION The ADCA3992 is a high gain, power doubler hybrid amplifier high electron mobility transistor (pHEMT) die in combination optimized for a wide range of bias conditions for power with a gallium nitride (GaN) HEMT die. The dc current and efficiency and customer flexibility. The ADCA3992 is ideally supply voltage can be adjusted externally for optimum distortion suited for use in digital predistortion (DPD) node designs for performance vs. power consumption over a range of output maximum power savings. The device achieves extremely high levels. The ADCA3992 is packaged in the industry-standard SOT115J package. RF output, up to 76.8 dBmV composite power, or 67 dBmV virtual level, using a gallium arsenide (GaAs) pseudomorphic Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
