When I published the appnote on filler and ground effect for a 60GHz balun, there were many comments and questions on the ground cutout. It seems that many designers didn’t realize the possible loss in performance from a ground cutout that is too small. That’s enough reason to adress the issue and a possible solution […]
60 GHz on-chip balun transformer
Published on 17, Jul
Two new appnotes discuss the design of a 60GHz on-achip balun with 2:1 turn ratio. Part 1 investigates the 60 GHz balun shape: Interleaved or overlay? Interleaved or overlay? Part 2 of the 60 GHz balun application note investigates effect of dummy metall placement on insertion loss. Dummy metal fill effect

ADS: Sweep over many S-Parameter files: look up table or sprintf()?
Published on 21, Jun
In this application note, we look at two methods of sweeping over a list of S-parameter files: using a look up table and using sprintf() string function to build filenames. Sweep over many S-Parameter files: look up table or sprintf()?
