De-embedding in MicrowaveOffice

"Pascal Steiss"

** Microwave Office is a prime example of an overcooked program which suffers from excessive padding - there certainly are a lot of somnambulist bed bugs embedded all that software.

Any box so well padded would be completely anechoic, for sure.

I don't know about Microwave Office, but for Network Analyzers the technique allows you to eliminate the effects of the test fixture, which lets you look more accurately at the behaviour of the DUT alone.

When in doubt, give the folks at AWR a call and ask them...

BTW - usually, it is to isolate a section of the circuit to analyze just that section, eliminating other parts of the design for this analysis...

De-embedding just means to remove a portion of a transmission line. In other words, if your device is transmission line C = transmission line A cascaded with transmission line B, then de-embedding A from C would give you B.

As someone else wrote, this is often used to eliminate fixture effects in measuring a device with a VNA.

There are explicit equations how to do this knowing the s parameters of the two elements.
