K-Band PA Triples Bandwidth, Shrinks Power Draw, Saves Space in LEO Satellites
Browse our complete IMS 2025 coverage.
At IMS 2025, Qorvo (Booth #543) will display its latest K-band power amplifier (PA) designed to improve the performance and integration of low-Earth-orbit (LEO) satellites. With next-generation payload demands evolving, the QPA1722 exploits GaN-on-SiC technology to give system designers a more efficient, compact, and scalable option for space-based payloads.
Qorvo’s QPA1722 PA offers customers 3X the instantaneous bandwidth, a 38% smaller footprint, and 10% higher efficiency than competing devices, it’s claimed. These enhancements enable greater data throughput and more flexible payload architectures, critical for meeting global connectivity goals in size- and power-constrained satellite platforms.
Some of the banner specs of the QPA1722 include:
- Frequency range: 17.7 to 20.2 GHz
- Output power: 10 W (saturated); 6 W (linear)
- >1-GHz instantaneous bandwidth for high-data-rate applications
- 36% efficiency for improved power handling and thermal management
- Compact SMT package for streamlined system integration
The QPA1722 is sampling now, with volume production planned for the fall of 2025. Qorvo also provides evaluation kits upon request.
