Dennis,
Sorry for the errors. It should be
MTT-Vol.45,No.7,1997,pp.1071-1077.
The title is "Pure-Mode Network Analyzer for On-Wafer Measurements of
Mixed-Mode S-Parameters of Differential Circuits" by David E. Blockelman
etc.
Thanks for pointing it out.
Mick

I looked on the MTT web site and did not find the article that you
mentioned below. The pages in No. 1 start at 1, the july issue has pages
in the 1000 to 1100 range but no article starting on page 1071. What is
the title of the paper?
Thanks
Dennis
