A Multiport S-Parameter Plotting Utility
, of pSemi, sent me a note about the company's new "sNp Viewer" multiport s−parameter
plotting software that is available for free downloading on the pSemi website. It
is provided as an executable file that installs the Runtime Vee (Keysight) framework
needed for the program's operation. Look for the sNp Viewer icon to appear
on your desktop (not in the Start menu) when installation is complete. You can drag
the icon into the Start menu afterwards. My guess is this was a tool developed for
internal use by the engineering staff and it turned out so well that they decided
to make it available to everyone; it is quite handy.
The example screen shot at the right uses the pSemi*
SP3T Reflective RF Switch, which is a 4-port device with a .s4p data file extension.
I wanted to use a device with more than just two ports. The plots would get really
busy if the PE42412
UltraCMOS® SP12T RF Switch was used with its .s13p data files! Shadowed items on
image are things I added for additional information.
* The datasheet
shows Peregrine Semiconductor,
pSemi's former handle.
