QPA4346D 37.5 – 42.5 GHz 6 Watt GaN Power Amplifier Product Overview Qorvo's QPA4346D is a high power MMIC amplifier fabricated on Qorvo's production 0.15 um GaN on SiC process (QGaN15). It is targeted to the 37.5 - 42.5 GHz Satcom Q-V band. QPA4346D achieves 3 W linear power with 25 dBc third order intermodulation distortion products, and 16 dB small signal gain. It provides 6 W of saturated output power while achieving 20% power-added efficiency. To simplify system integration, the QPA4346D is fully matched to 50 ohms with integrated DC blocking caps on both I/O ports. Its RF ports are DC coupled to ground for optimum ESD performance. The QPA4346D is ideal for supporting communications and radar applications in both commercial and military markets.
