/ pSemi Launches UltraCMOS+™ Showcasing 16 Generations of Platform Advancements

New technology delivers orders-of-magnitude improvements in RF and mixed-signal performance

SAN DIEGO – June 11, 2025 – pSemi^® Corporation, a Murata company leading in the design and development of semiconductor integration and advanced connectivity, today unveiled its latest breakthrough in RF silicon-on-insulator (SOI) platform technology: UltraCMOS+^™. Advancing the performance of legacy and patented UltraCMOS^®technology, UltraCMOS+ enables pSemi to offer the next generation of monolithic integration with vast improvements in power handling, linearity, isolation, R_ON, C_OFF, integrated intelligence, and ultimately portfolio expansion.

As the single source of advanced silicon-on-sapphire (SOS), pSemi has developed a unique team of process engineers, IC designers, and software engineers to advance the technology. The result is the development of the UltraCMOS RF SOI platform, which includes proprietary semiconductor processes, product development kits (PDKs), simulation software, and unique circuit techniques.

Over the last decade, pSemi transitioned its focus from SOS to SOI but maintained its unique team and continued the advancement of UltraCMOS. The pSemi team and company culture enabled the rapid development of 16 generations of UltraCMOS, expanding the usage model while also optimizing performance for targeted RF functions.

“The introduction of the UltraCMOS+ platform represents a decade of advancements that were delivered to our internal parent company Murata. Launching this next-generation platform to our historical markets will once again change the way our customers design and architect their RF products.”
