The Mini-Circuits USB-8SPDT-A18 is a general-purpose, USB-controlled RF switch matrix containing eight electromechanical SPDT, absorptive fail-safe RF switches for greater efficiency for RF and microwave test set-ups. It is constructed in break-before-make configuration and powered by +24 VDC  with a switching time of 25 ms typical.

The  eight absorptive switches allow for a large number of presets, such as dual transfer switches, 2 in/8 out, an SP9T, or 2 in/6 out plus an SP3T.  Any design configuration can be saved, with all jumpers and switch states clearly indicated for quick recall and set-up, or as a handy reference when working on future projects.

The RF switches can be operated in all these configurations remotely using the supplied GUI program, or programmed by the user using the included API DLL com object. They also operate over a wide frequency band from DC to 18 GHz, have low insertion loss (0.2 dB typical) and high isolation (85 dB typical), making the switch matrix suitable for a wide variety of RF applications.

The switch matrix enables testing of multiple parameters or multiple DUTs in a single pass, without stopping to connect/disconnect cables.
