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
