Data Sheet

FEATURES

GENERAL DESCRIPTION

Total composite power: 74 dBmV

High power gain: 25.0 dB at 1218 MHz

Excellent linearity

Very low distortion

Composite triple beat: −80 dBc typical

Composite second-order: −78 dBc typical

Carrier to intermodulation noise: 58 dB typical

Low noise figure: 3 dB at 45 MHz and 4 dB at 1218 MHz

Unconditionally stable

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.

Transient and surge protection

APPLICATIONS

45 MHz to 1218 MHz community access television (CATV)

infrastructure amplifier systems

Remote physical layer (PHY)

DOCSIS 3.1 compliant
