Dow-Key® Microwave Announces New Miniature MS-Series Matrix Product Launch


Dow-Key Microwave introduces a new product generation of switch matrices: The Miniature MS-series Matrix.

This mini matrix is an ideal switch solution for Test & Measurement requirements; designed and built with the Reliant Switch™ product series in mind. It is equipped with high performance Reliant Switches™ with 0.03 dB insertion loss repeatability across DC to 26.5 GHz and a minimum 5 or 10 Million Life Cycles.

The miniature sized enclosure can be populated on the front panel with maximum of:

  • (8) SPDT Reliant Switches™
  • (2) SP6T Reliant Switches™
  • (1) SP6T + (4) SPDT Reliant Switches™
  • (2) SP6T + (1) SPDT Reliant Switches™

The MMS-series needs 12Vdc power supply and the switches can be controlled remotely via TCP/IP Ethernet and HTTP-Server, which has a built-in “Sequencer” feature that allows the user to program up to ten 500-step sequence programs.

“We are thrilled to introduce a miniature switch matrix to our matrix product portfolio,” says Matrix Sales Product Manager, Sara Nazemzadeh. “It’s designed for the test & measurement industry where bench tests can easily be performed using Dow-Key’s MMS-series Matrix.

For instance, a test engineer can extend the ports on his/her Vector Network Analyzer (VNA) by adding a switch box to each VNA port, which would extend each VNA port to 12 ports.

The MMS-series can be used in many applications where RF switches are needed and it is not restricted to VNA’s extension only. Furthermore, to support extensive testing on DUT’s, the MMS-series matrix model is equipped with high performance switches with 0.03 insertion loss repeatability and with minimum of 5 Million or 10 Million life cycle switches, “added Ms. Nazemzadeh.
