A121 Overview

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 pico-

second 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.

Applications

• High precision distance measurements with

mm accuracy and high update rate

• Proximity detection with high accuracy and

the possibility to define multiple proximity

zones

• Motion detection and velocity measurement

• Material detection and classification

• High precision object tracking, enabling

robot navigation

• Gesture control

• Monitoring of vital life signs such as

breathing and pulse rate
