DOCSIS 3.1 Power Doubler Hybrid Module, 45 MHz to 1218 MHz Data Sheet ADCA3950 FEATURES GENERAL DESCRIPTION Total composite power: 74 dBmV The Analog Devices, Inc., ADCA3950 is a power doubler High power gain: 25.0 dB at 1218 MHz hybrid module packaged in the industry-standard SOT-115J Excellent linearity package. The device achieves a high RF output of 74 dBmV Very low distortion total composite power under 18 dB tilt conditions by using Composite triple beat: 80 dBc typical advanced circuit design techniques with gallium arsenide Composite second-order: 78 dBc typical (GaAs), pseudomorphic high electron transistor (pHEMT), Carrier to intermodulation noise: 58 dB typical and gallium nitride (GaN) HEMT technologies. The ADCA3950 Low noise figure: 3 dB at 45 MHz and 4 dB at 1218 MHz provides high gain, simplifying the design and manufacturing Unconditionally stable of DOCSIS 3.1 infrastructure equipment.
