Dow-Key Microwave is another maker of GPIB-controlled RF relays. best, Mark Alexander Device Power and Signal Integrity, Xilinx Inc. -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Peter.Pupalaikis@xxxxxxxxxx Sent: Wednesday, November 16, 2011 1:44 PM To: Ming Li Cc: si-list@xxxxxxxxxxxxx; si-list-bounce@xxxxxxxxxxxxx Subject: [SI-LIST] Re: switch matrix Hi Ming: I'm assuming you want relays - because you can buy pin-diode switches too - but you'll lose DC. As far as relays, you have DowKey, Ducommun, Radiall, and Teledyne to choose from. I like Radiall the best - they are hard to deal with but seem to make the highest quality, albeit expensive product. You can also buy instruments that have these relays in them that can be controlled via GPIB so you don't have to build your own switching system. Pickering is a company that sells these. Not sure of others.

Maximum frequency is 10GHz. Can anyone give us some suggestions? Thanks. We appreciate your help.
