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.

The QPA4346D is 100% DC and RF tested on-wafer to

ensure compliance to electrical specifications.

Lead-free and RoHS compliant
