Adjustable Current Optimizes Power Doubler Distortion Performance

RFMW announces design and sales support for a GaAs pHEMT/MESFET and GaN HEMT amplifier module. The Qorvo QPA3333 Power Doubler provides 28 dB of gain for DOCSIS 3.1 amplifiers and broadband CATV hybrid modules from 45 to 1218 MHz. Using a single 24V supply, the QPA3333 offers excellent linearity, superior return loss and low noise which provides optimal reliability. By adjusting DC current, distortion vs. power consumption can be optimized over a wide range of output levels. Offered in an 11 x 8.5 mm package.
