Qorvo QPA2211 27.5–31GHz 10W Ka-Band GaN Power Amplifier
Qorvo QPA2211 Ka-Band GaN Power Amplifier
The QPA2211 from Qorvo is a 27.5–31GHz Ka-band GaN power amplifier developed for satellite communications and 5G infrastructure. It provides approximately 5W linear output power and more than 10W saturated output power.
The amplifier uses Qorvo’s 0.15µm QGaN15 GaN-on-SiC process and is supplied in a bolt-down package with a copper base for improved thermal management. Qorvo currently lists the QPA2211 as a production product.

Applications and Integration
The QPA2211 is primarily intended for:
Ka-band satellite communication transmitters
SATCOM uplink equipment
Commercial and defense communication systems
5G millimeter-wave infrastructure
High-power Ka-band RF modules
The RF input and output are internally matched to 50Ω and include integrated DC-blocking capacitors. The bolt-down copper-base package provides a direct thermal path to the system heat spreader or chassis.
Frequently Asked Questions
Is the QPA2211 a 10W linear amplifier?
No. The QPA2211 provides approximately 5W linear output power. Its 10W rating refers to saturated output-power operation.
Is the QPA2211 suitable for Ka-band SATCOM uplinks?
Yes. Its 27.5–31GHz frequency coverage is designed for Ka-band satellite communications and related high-frequency transmitter systems.
Does the QPA2211 require external RF matching?
The RF input and output are internally matched to 50Ω and include integrated DC-blocking capacitors. External bias, decoupling and thermal-management components are still required.
What is the advantage of the copper-base package?
The bolt-down copper base provides a low-resistance thermal path between the amplifier and the system heat spreader, which is important for reliable high-power operation.
Is a QPA2211 evaluation board available?
Yes. The QPA2211EVB is available for laboratory evaluation and prototype development.
