PseudolithIC Inc. Raises $6M in Seed Funding to Revolutionize Wireless Chips with Proprietary Chiplet Heterogeneous Integration Technology.
Hybrid approach pushes the boundaries of RF technology
Enables cost-effective solutions for next-gen 5G/6G networks, satellite communications and autonomous systems
Product samples will be available in the coming months
PseudolithIC Inc., an innovative leader in RF (radio frequency) chipset products, today announced it has successfully raised $6 million in a seed funding round. The round was led by Entrada Ventures, with additional investments from Foothill Ventures and Uncork Capital.
The investment will enable the company to accelerate the development and commercialization of hybrid semiconductor products which integrate compound semiconductor chiplets into silicon wafers, aiming to transform both the technical performance and the economics of the RF and millimeter-wave communication industry.
Silicon, the workhorse of the semiconductor industry, offers uniform processing, high manufacturing efficiency and low cost. Compound semiconductors, however, are constructed with specialized processing, and while they offer enhanced performance, particularly at higher frequencies, these materials are fabricated on smaller wafers and are more expensive to produce.
The PseudolithIC chip offers the high performance of a monolithic microwave IC (MMIC), but at a fraction of the cost. The company’s proprietary technology integrates high-performance compound semiconductor chiplets with low-cost 300mm silicon wafers, offering a superior blend of performance, power efficiency, and scalability for RF applications. This next-generation approach addresses key challenges in wireless communications, particularly for fast-growing and critical industries such as terrestrial and satellite communications, aerospace, and IoT (Internet of Things) applications.
“Our team is excited to push the boundaries of what is possible in RF technology,” said Jim Buckwalter, CTO of PseudolithIC and Professor of Electrical and Computer Engineering at UC Santa Barbara. “The hybrid approach of combining silicon and compound semiconductor chiplets unlocks new potential for RF systems, enabling faster data rates, lower latencies, and better reliability. We believe our innovations will be game-changing for customers requiring high-performance wireless solutions.”
PseudolithIC is based in Santa Barbara, CA, and currently has a dedicated team of more than 15 employees, all focused on advancing the company’s pioneering products. The fresh infusion of capital enables the company to expand its team and accelerate research and development to bring its products to market.
"We're really enthusiastic about leading PseudolithIC’s seed round,” said Alex Fang, Managing Partner at Entrada Ventures. “The wireless industry has been limited by the opposing metrics of performance and scale. We think Florian and Jim have developed something here that will unlock a new era in wireless systems that will result in unprecedented performance on mobile and satellite platforms."
Florian Herrault, CEO of PseudolithIC, said, “We are thrilled to have the backing of such investors as Entrada Ventures, Foothill Ventures, and Uncork Capital. Our goal is to lead the charge in providing cost-effective, high-performance silicon RFIC solutions augmented with compound semiconductors, that meet the ever-growing demands of next-generation wireless systems.”
