产品详情

The ADCA3990 is a power doubler hybrid module packaged in the industry-standard SOT115J. The device achieves extremely high RF output, up to 76.8 dBmV composite power or 67 dBmV virtual level, by using advanced circuit design techniques, such as gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) die and 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.

Applications

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