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 ideal y supply voltage can be adjusted external y 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 RF output, up to 76.8 dBmV composite power, or 67 dBmV SOT115J package. virtual level, using a gallium arsenide (GaAs) pseudomorphic
