CXWL0009 - Functional Block Diagram
Description
The CXWL0009 is a highly-integrated monolithic ultra-wideband (UWB) motion detector RFIC that integrates the transmit output amplifier and the full receive path. The transmit power level is adjustable along with the detection range. The radar is a homodyne configuration for simplicity and small size. An integrated RF oscillator provides the carrier frequency for the Tx pulse and the local oscillator (LO) for the receive mixer. The homodyne radar architecture helps to reduce the power consumption. An I²C digital interface is used to communicate and configure the CXWL0009 for the desired configuration.

Social Distancing Wristwatch with UWB
I'm wondering if Renesas still makes the UWB social distancing watch from 2020 with Altran as I'm interested in it for a new activity app
