ARI UNI42 60GHz Radar Module

1. Introduction

The UNI42 radar module from Augmented Radar Imaging is an easy-to-use board that contains 60-GHz

mmWave Radar transceiver with patch antennas etched on PCB and acts as a Radar front-end module. It can

be used in various applications where object detection, distance measurement, or speed measurement are

required. The radar module is equipped with 12-pin and 32-pin connectors to interface external peripherals and

host boards so that the users can customize for their specific applications.

2. Hardware Features

2.1. Features

 Radar tuning frequency: 60-64GHz

4. Regulatory Compliance 4.1. Operational Considerations TheUNI42 Radar module is designed to transmit at power level that meets the FCC EIRP peak power requirement. The host manufacturer does not have the ability to adjust the output power. 4.2. RF Exposure Considerations In accordance to the EN 62311 RF exposure test on the Radar transceiver, a minimum separation distance of 20 centimeters should be maintained between the user and the UNI42 Radar module during operation.

IC ES-003 compliance through testing with the UNI42 module installed. 4.5. FCC Statements per 47 CFR §15.105 Class B Device Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
