Qorvo QM35825 UWB Low-Power System-on-Chip (SoC)
Qorvo QM35825 Ultra-Wideband (UWB) System-on-Chip (SoC) is a low-power and fully integrated solution compliant with IEEE 802.15.4-2024. This module is designed for excellent Rx sensitivity and low power consumption. The QM35825 is optimized for consumer, enterprise, and industrial applications, supporting FiRa™, Aliro, and Omlox ranging schemes with an accuracy of ±5cm and AoA at ±2°. Additional features include on-chip computing for ranging, angle-of-arrival (AOA) processing, radar, and data transfer. The QM35825 UWB SoC from Qorvo integrates four flexible RF ports, LNAs, PA, and RF switches, a Cortex®-M33 with Secure Enclave, and a host of security features and communication peripherals.
Qorvo recommends the ACT88329 PMIC as the ideal choice for powering QM35825 applications, with its default configuration specifically optimized to meet the unique requirements of the QM35825 systems.
