Teledyne Relays has developed three new series of miniature switch matrices that combine Teledyne’s 50 Ω electromechanical coaxial switches with remote control. The MMA series controls up to four SPDT switches with three frequency band options: DC to 18 GHz, DC to 26.5 GHz or DC to 40 GHz. The MMB series controls up to four transfer switches covering DC to 18 GHz. The MMC series controls one or two SPMT switches (SP3T, SP4T, SP5T or SP6T) with three frequency range options: DC to 18 GHz, DC to 26.5 GHz or DC to 40 GHz. Switch matrix RF interfaces are SMA or 2.92 mm connectors. The operating temperature range is -40o to +65oC, and the switch actuators have a typical life of five million cycles.

Remote operation is accomplished with TCP/IP commands to the matrix’s Ethernet interface. Switch control is also accessible using a USB virtual serial port and the provided command set. The interfaces enable the coaxial switch to be set to the desired position and the position read back to verify switching. The miniature switch modules features a graphical user interface (GUI) that enables the user to control the switches through graphical icons and visual indicators, instead of text-based interfaces or typed command labels. The interface is compatible with multiple system platforms, including NI’s LabVIEW, which enables quick device interfacing and integrating switch control with existing programming.

Teledyne Relays has a heritage in military programs that spans more than 50 years. Teledyne Relay products are also used in industrial, commercial and medical applications.
