Tutorial, experiment and teardown of a 24GHz Doppler radar module

CDM324-e1534131460412

Shahriar posted a detailed analysis of a CDM324 24GHz Doppler radar module from IC Station:

Opening the module reveals a series of microwave PCB components and several active devices. A complete analysis of the module is presented. The unit is then measured and the impact of antenna impedance and power supply voltage on the output frequency is measured. The phase noise of the output signal is also measured. Using a series of servo motors, the radiation pattern of the antenna array in both azimuth and elevation is also presented.

More details on The Signal Path blog.
