RFMW, Ltd. announces design and sales support for a unique CATV power doubler from Qorvo. By adjusting DC current via an additional pin out, the QPA3238 allows distortion optimization versus power consumption over a wide range of output levels. Operating from 45 to 1003MHz, return loss is 17dB for faster design times. Gain is 22.5dB minimum with a low noise figure of 4dB. The QPA3238 draws 480mA maximum from a 24V supply and is offered in a SOT-115J package.
