Eridan

Eridan is a semiconductor and telecommunications company that has developed the world’s first all-digital, polar modulation-based radio unit for wireless networks. The company’s proprietary Ultra-Clean Signal technology delivers unmatched spectral efficiency, enabling 5G networks that consume up to 5 times less power than legacy systems while providing breakthrough coverage to the cell edge. Eridan’s fully digital radio units are engineered for AI-era applications, private 5G deployments, and rural broadband, making networks simpler to deploy, more efficient to run, and capable of handling surging demand from autonomous devices and augmented reality. Field tests have sustained over 100 Mbps at 1.7 km using just 0.3W, demonstrating that clean signal technology outperforms brute-force power approaches. The company has integrated its radios with OCUDU’s open-source CU/DU software for a complete U.S.-developed 5G Open RAN solution. Founded in 2013 and headquartered in Sunnyvale, California, Eridan has raised approximately $16 million in Series B funding. Investors include Capricorn, Social Capital, Mountain View Capital, Diamond Edge Ventures, DARPA, NTIA, and Pendrell. The company has approximately 106 employees.
