Ventura, California – October, 2004

Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, switch matrices, integrated modular assemblies, and related passive components. Its newest product, a CANbus-based Switch Matrix System with Ethernet control interface, performs from 20 to 200 MHz and is available in full fan-out configurations from 6X6 to12X12.

To compensate for system insertion loss, all inputs are outfitted with high linearity amplifiers. The EWAB version of this product can be easily accessed from anywhere in the word via TCP/IP protocols on 10Base-T networks using HTTP 1.0 interface. While the 3204 Switch Matrix is designed for signal routing applications, it can also be utilized as a building block for numerous ATE applications.

Each unit is equipped with a Windows-based PC computer and front-panel, touch screen for manual override and is housed in a low profile 3U rack mountable chassis. This CANbus-based Switch Matrix offers an enclosure and redundant power supplies matched for EMI integrity. Impedance is 50 Ω.
