Mini-Circuits’ RC-3SPDT-A18 is a general purpose RF switch matrix controlled via either USB or Ethernet-TCP/IP (supports HTTP and Telnet protocols). The model contains 3 electromechanical SPDT, absorptive fail-safe RF switches constructed in break-before-make configuration and powered by +24VDC with switching time of 25 ms typical. The RF switches 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 perfectly suitable for a wide variety of RF applications.
The RC-3SPDT-A18 is constructed in a compact, rugged metal case (4.5” x 6.0” x 2.25”) with 9 SMA (F) connectors (COM,1 and 2 for each switch) USB type B port, standard RJ45 network socket and DC power input.
