S-parameters In RF testing – simple explanation

by 2 Comments

S-parameters are mathematical representation of energy propagation within a multiport electrical network. It is written as a complex matrix file also knows as scattering parameters. S-parameter file represents full combination of the reflection and transmission parameters in a multiport network with frequency component. It gives an idea of how the DUT behaves with a signal in both forward and reverse direction.

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. [Read more…] about Inter Modulation Distortion In Passive Devices
