The MS85001 is a highly-integrated monolithic ultra-wideband (UWB) motion detector radio-frequency IC (RFIC) that integrates the transmit output amplifier and the full receive path. The transmit power level and the detection range are adjustable.

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 set up the MS85001 for the desired configuration.
