Analog Devices Inc. ADCA3992 CATV Power Doubler Hybrid
Analog Devices Inc. ADCA3992 CATV Power Doubler Hybrid is optimized for a wide range of bias conditions for power efficiency and flexibility. The ADCA3992 is ideal for digital predistortion (DPD) node designs to maximize power savings. The device achieves extremely high RF output, up to 76.8dBmV composite power, or 67dBmV virtual level. The device uses 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.
