A111 Overview

The A111 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 A111 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 in Package (AiP). This

will enable easy integration into any portable

battery driven device.

The A111 is based on leading-edge patented

sensor technology with pico-second time

resolution, capable of measuring absolute

distance with mm accuracy up to a range of

2 m (1) and with configurable update rate.

The A111 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

• Ultra-low power consumption, e.g. average

power consumption 0.2 mW at 0.1 Hz update

rate, 3 mW at 10 Hz update rate and 20 mW

at 100 Hz update rate

• Proximity detection with high accuracy and

the possibility to define multiple proximity

zones

• Motion detection, Speed detection

• Enables material detection

• High precision object tracking, enabling

gesture control

• High precision tracking of 3D objects

• Monitor vital life signs such as breathing and

pulse rate

(1) 2m ranging is guaranteed for an object size, shape and dielectric properties corresponding to a spherical corner reflector of 5 cm radius.
