Inter Modulation Distortion is one of the important parameter of linearity in every RF and microwave components. Intermodulation happens whenever multiple signals at two or more frequencies interact in any passive or active devices. IMD is one of the significant factor which limiting the system capacity in modern wireless communication system.
Second Order Intermodulation
Two tone Intermodulation (Third Order – IMD3)

Note: The test setup need to be configured based on the power requirement, device specification, test setup limitation and environmental conditions etc.
