Qorvo's QPA4003 is a Ka-band power amplifier fabricated on Qorvo's 0.15um GaN on SiC process (QGaN15). Operating from 26.5 to 29.5 GHz, it achieves 1.25 W linear power with lower than −33 dBc intermodulation distortion products and 29 dB small signal gain. Saturated output power is greater than 37 dBm (5 W) with an associated power-added efficiency of 22 %.

The QPA4003 is packaged in a 5.0 x 5.0 mm laminate package. It can support a variety of operating conditions to best support system requirements. With good thermal properties, it can support a range of bias voltages.

The QPA4003 is fully matched to 50 ohms. RF I/O power are shorted to ground. The QPA4003 is ideally suited to support satellite communications and 5G infrastructure.
