Image of SPARK Microsystems SR1120AA-MD318-MP1 Wireless UWB Module The SR1120 module from SPARK Microsystems is an ultra-wideband (UWB) wireless module designed for real-time, low-power applications. Operating in the 6.2 GHz to 9.5 GHz band range, it features an agile reconfigurable PHY optimized for interference resilience, energy efficiency, and time-sensitive communication with support for high data rates.

Ideal for wireless audio streaming, peripherals, wearables, robotics, industrial control, IoT, and even medical interfaces, the SR1120 module enables developers to build responsive, power-efficient wireless systems.

The module supports symbol rates up to 40.96 MHz and delivers very low latency, with 25 μs airtime for 1 kbit transmissions. In addition to robust data communication, it offers proprietary low-power ranging functionality.

With robust interference immunity and seamless coexistence alongside BLE, Wi-Fi (2.4 GHz, 5 GHz, and 6 GHz), and cellular systems, the SR1120 module is well-suited for modern short-range wireless designs that demand high responsiveness, high performance, and energy-conscious operation.
