Hello everyone,
we have three cascaded RF components on an our transmitter and we want to calculate the total loss, taking into account the insertion loss of each components, insertion loss of the microstrips used for the layout and the mismatch loss between a component and the other one.
We have the de-embedded S-parameters of the three components obtained from the manufactures, and S-paramters of all microstrips that link them, derived by electromagnetic simulations.
We know that we can convert the S-paramters into T-parameters and calculate the total loss by multipling the individual matrixes with each other. But we are not very sure of result, because of the fact that the S-paramters of components are de-embedded while we have placed the excitation ports for the microstrips under the input and output PADs of the components in order to have the S-parameters of the microstrips.
May you help me to understand if the calculation approach is right?
Many thanks.
Best regards,
Antonio
