The 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.
