pSemi offers a complete support package of tools and technical expertise to simplify mmWave design and development.
The PE188200A-Z beamformer IC (n257 band) and PE128300A-Z up-down converter IC (n257, n258 band) offer a wide range of features and benefits to 5G FR2 system designers.
Smallest footprint per channel
Monolithically integrated RF SOI ICs with the industry's smallest form factors make it easy to build large arrays without the need for extra routing.
Full IF-to-RF coverage
Up-down converters can be paired with up to four pSemi beamformers to support massive-MIMO, hybrid-beamforming and other active antenna configurations.
Applications
