Product Details

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.


  • 45 MHz to 1218 MHz community access television (CATV) infrastructure amplifier systems
  • Remote physical layer (PHY)
  • DOCSIS 3.1 compliant
