The BGT60TR13C MMIC is a 60GHz radar sensor with integrated antennas and comes with one transmitting and three receiving antennas. Thanks to the L-shaped antenna array, horizontal and as well as vertical angular measurement can be ensured. Moreover, the Antennas in Package (AIP) concept eliminates the antenna design complexity at the user end and the PCB can be designed with standard FR4 materials.

BGT60TR13C MMIC enables ultra-wide bandwidth FMCW operation in a small package (6.5 x 5.0 x 0.9 mm³) and is equipped with an integrated Finite-State Machine (FSM). With the aid of the FSM, BGT60TR13C can perform FMCW frequency sweeps (so-called chirps), data acquisition as well as storing of samples into the internal FIFO memory autonomously. Thanks to optimized power modes during sensor operation, lowest power consumption of <5mW (duty cycle) can be guaranteed. Further reduction of average power consumption will be ensured via DC duty cycling.

Thanks to the ultra-wide bandwidth of 5.5 GHz a very low range resolution down to ∼3cm can be offered and in cooperation with a ramp-up speed of 400 MHz/μs a higher doppler velocity achieved. In addition, the high Signal-to-Noise Ratio (SNR) ensures detection of people up to 15 m, front facing towards the sensor, while high sensitivity allows detection of movements down to sub-millimeter. Via the very commonly used SPI (Serial Peripheral Interface) the host MCU first configures the sensor, then reads the acquired sensor data, and finally performs the application-specific signal processing steps.

With its small form factor and low power consumption, BGT60TR13C MMIC brings innovative, intuitive sensing capabilities to many applications. Based on the developed algorithm the MMIC can serve established as well as new applications and use cases without intruding on privacy. Thanks to its feature-set, the MMIC can measure velocity, angle, horizontal as well as vertical.

Please be aware that the algorithm to serve these use cases needs to be developed separately in cooperation with partners/signal processing experts.
