Tower Semiconductor Announces a New RF Switch Technology with Breakthrough Performance

Enables cutting-edge solutions for 5G and high-performance RF switch markets with record Figure of Merit performance: Ron x Coff less than 10 femtoseconds

The new technology will be presented at IMS 2020, with MPWs available in 2021

MIGDAL HAEMEK, Israel, August 03, 2020 – (NASDAQ/TASE: TSEM), the leader in high-value analog semiconductor foundry solutions, today announces a new radio frequency (RF) switch technology with record figure of merit targeting the 5G and high-performance RF switch markets. This new switch technology enables more efficient, novel RF system architectures in applications including mobile, base-station and mmWave communications. Tower Semiconductor is engaged with multiple customers and partners to bring this technology to market for next-generation products.

This new switch technology demonstrates a record RF device figure of merit: Ron x Coff < 10 femtoseconds vs. 70-100 femtoseconds in use today for the most advanced applications. The switch performs over an extremely wide range of frequencies spanning MHz to all frequency bands discussed for 5G, and further into the mmWave. This results in extremely low insertion loss and very small device size.

The switch is also nonvolatile so consumes no energy when in the on-state or off-state, making it attractive for IoT, and other power and battery sensitive product applications. Finally, Tower has demonstrated the versatility of this patented technology by integrating it with some of its other process platforms such as SiGe BiCMOS and Power CMOS.

Tower Semiconductor will be offering multi-project wafer runs (MPWs) in 2021 for select customers.

The new RF switch will be presented at (International Microwave Symposium) with results from electrical devices, process integration and circuits fabricated at Tower Semiconductor. Presentations are part of the session (Tu1G-2 and Tu1G-5).

The Live Stream event will take place Aug. 4 – 6, 2020. For more details about the presentations, please visit IMS 2020 event website.
