The Analog Devices, Inc., ADCA3950 is a power doubler
hybrid module packaged in the industry-standard SOT-115J
package. The device achieves a high RF output of 74 dBmV
total composite power under 18 dB tilt conditions by using
advanced circuit design techniques with gallium arsenide
(GaAs), pseudomorphic high electron transistor (pHEMT),
and gallium nitride (GaN) HEMT technologies. The ADCA3950
provides high gain, simplifying the design and manufacturing
of DOCSIS 3.1™ infrastructure equipment.
