The radar sensor is based on pulsed coherent radar technology and combines extremely low power consumption with high accuracy. The unique characteristics of this radar sensor make it possible to identify materials and detect motion in advanced sensor applications. The small size, only 5×5 mm, and low power consumption are ideal for compact battery-driven and mobile devices. In mid 2022, Acconeer broke the milestone of more than 1 million shipped sensors to over 60 countries.
A121
The A121 is a radar system based on pulsed coherent radar (PCR) technology and is setting a new benchmark for power consumption and distance accuracy – fully integrated in a small package of 29 mm2.
The A121 60 GHz radar system is optimized for high precision and ultra-low power, delivered as a one package solution with integrated Baseband, RF front-end, and antenna. This will enable easy integration into any portable battery driven
device.
The A121 is based on leading-edge patented pulsed coherent radar technology with picosecond time resolution. The sensor can measure up to 20 meters and the actual measurable distance is dependent on object size, shape, and dielectric properties.
The A121 60 GHz radar remains uncompromised by any natural source of interference, such as noise, dust, color and direct or indirect light.
