Tip of the Month
Extracting multi-port transmission line models from S-parameter files
With the new 'sparam_to_tline' utility, you can now extract a multi-port transmission line model including all the port-to-port transfer functions such as reflections and crosstalks from an S-parameter file.
Primitive of the Month
