GENERAL DESCRIPTION

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.
