Said to be the first-of-its-kind, this CMOS-based single-pole/ten-throw (SP10T) switch has been engineered to meet the demanding requirements of the land mobile radio (LMR) market, including critical communications for first responders, firefighters, law enforcement, and military personnel.

The high-power switch provides support for LMR applications and is also versatile enough to serve a variety of sectors including defence systems and advanced wireless infrastructure.

I has been optimised for high-reliability switching tasks, and the MBX3110 can be used to replace pin diodes in sophisticated test equipment, underscoring its broad utility across multiple industries. In addition, solid-state RF switches like the MBX3110 outperform equivalent electromechanical switches in most applications, offering greater reliability, faster switching speeds and longer lifetimes.

“The introduction of MBX3110 SP10T switch sets a new industry standard for high-power RF switching,” claimed Fabian Battaglia, CEO of Mobix Labs. “We designed this new RF switch to support the wider bandwidth required by the LMR market to ensure uninterrupted access and a clear, reliable signal. Its high linearity, low insertion loss, and rapid switching capabilities enable it to perform in the most demanding environments, pushing the boundaries of what's possible in RF applications.”

The global RF switch market is poised for significant growth and is projected to expand from $13 billion in 2021 to $60 billion by 2032, as reported by the research firm Global Market Insights.

High-Power Performance: The MBX3110 RF switch offers impressive performance at a low cost, featuring wider frequency range, lower insertion loss, and faster switching times compared to existing market offerings. These benefits enable users to extend the frequency range beyond the current spectrum without the need for external matching.

Optimised Specifications: The MBX3110 also boasts a low insertion loss of 0.52 dB at 1 GHz, high linearity of -78dBc at 43 dBm, and a rapid switching time of only 4 microseconds, ensuring best-in-class performance in demanding applications.

Compact Design: Packaged in a small 32-lead 5mm x 5mm QFN, the MBX3110 is suited for applications where both performance and size are critical, making it a versatile choice for a wide range of RF applications.

Samples of the MBX3110 SP10T switch are available now, and production volume is planned for Q3 2024.
