Description
K-LC7 is a small and low cost radar module which allows angle measurements. The module is operating in the 24.0 GHz to 24.25 GHz ISM band and it has a built in low phase noise VCO, which makes the module suitable for FSK or FMCW applications. The internal temperature compensating circuit keeps the output frequency stable over a wide temperature range.
IF outputs I and Q allow movement direction detection and high performance signal processing.
The sensor has a 3 x 4 patch radar frontend with an asymmetrical beam. The built-in voltage regulator covers a wide power supply range from 3.2 to 5.5V. The module provides a frequency divided output which can be used to measure the output frequency of the VCO.
