GaAs pHEMT/MESFET Power Doubler Amplifier: QPA3357

RFMW announces design and sales support for a GaAs pHEMT/MESFET 75-ohm Power Doubler amplifier. The Qorvo QPA3357 provides over 28 dB of flat gain and low noise of 4.5 dB for DOCSIS 3.1 amplifiers and broadband CATV hybrid modules from 47 to 1218 MHz.

 Using a single 24 V supply, the QPA3357 offers low noise and low distortion at high efficiency, consuming only 10.5 W of DC power in an industry standard SOT-115J package.

 With CSO of -81 dBc and CTB of -83 dBc, this amplifier provides 57 dBmV/ch virtual at 1.2 GHz, with 19 dB tilt.
