De-embedding in MicrowaveOffice

[Pascal Steiss]

Hi Community

Can anybody please tell me what De-embedding is used for in programs
like Microwave Office? Is it to eliminate box resonances?

Thanks
Pascal

** 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.
