Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: SMA-connector at the solderside Posted: Wed Oct 19, 2005 11:34 am
has anyone experience with sma-connectors mounted on the solderside of an rf-circuit. By doing this I can place the connectors at the optimal places on the board. But I don't know how to simulate the sma-to-microstrip transitions with sonnet.
Thank you fpr your help

Unfortunately you need a 3-D simulator. But the lumped element euivilent circuit is a inductor with a capacitor to ground. Inductor for the connector. The shunt capacitor models the coupling capacitanec to ground.

I don't have a 3D-Simulator. And the time to get familiar with such a tool may not be short. Or is there any 3D-simulator for free?
