Eridan

Eridan is a technology company that has developed a breakthrough radio technology called MIRACLE (Multiple Input Reconstituted Array for Communications with Low Energy). The company's patented solution is a lightweight, digital-to-RF system that eliminates the need for inefficient linear power amplifiers, making it highly energy-efficient.

At the core of Eridan's technology are custom-designed CMOS and GaN (Gallium Nitride) integrated circuits that enable the MIRACLE system to operate at 40-60% power efficiency, significantly higher than the 5-20% efficiency of traditional linear amplifier-based systems. This is achieved by leveraging switch-mode operation, which prioritizes the energy-efficient regions of transistor operation.

The MIRACLE system can instantaneously tune to any frequency between 600 MHz to 4.2 GHz, covering the entire cellular low-band below six GHz, with peak output powers of 10 watts. Moreover, it can switch on and off in nanoseconds, much faster than industry specifications, allowing for rapid capacity allocation and energy savings.

Another key advantage of Eridan's technology is its ability to encode more data into the same bandwidth through higher-order modulation techniques like 16k QAM. This means network operators can carry more data without increasing their spectrum usage, a significant benefit in the era of 5G and beyond.

Eridan's solution also simplifies equipment design, requiring smaller power cabinets and lower waste heat management, further reducing operational costs for network equipment. As of April 2024, the company plans to start sampling its radios and aims for commercial-scale production by 2026, initially targeting enterprise customers and municipal operators.
