The Analog Devices, Inc., ADCA3952 is a power doubler hybrid

module packaged in the industry-standard SOT-115J package.

The device achieves high RF output, up to 73.3 dBmV total

composite power with 9 dB tilt, by using advanced circuit design

techniques, such as gallium arsenide (GaAs), pseudomorphic

high electron transistor (pHEMT), and gallium nitride (GaN)

HEMT technologies. The dc current can be adjusted externally for

optimum distortion performance vs. power consumption over a

range of output levels. The ADCA3952 provides high gain,

simplifying the design and manufacturing of DOCSIS 3.1™

infrastructure equipment.

APPLICATIONS

45 MHz to 1218 MHz community access television (CATV)

infrastructure amplifier systems

Remote physical layer (PHY)

DOCSIS 3.1 compliant
