Ventura, California — June, 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. Dow-Key”s value driven RF Switching Solutions include Total Test Solutions that enable automatic testing of multi-port RF/Microwave components and subsystems. (Please visit our booth, ,1636, to see our demonstration). Dow-Key will also introduce its new family of electromechanical and solid state switching matrices, the latest addition to the suite of Dow-Key products and techniques aimed at meeting the most demanding needs of the growing RF/Microwave markets.

The demonstrated Automated Test Station is designed to test complex multi-port RF devices. It is based on the newest generation of Dow-Key’s 2 x 32 Switch Matrix, an Agilent PNA, and a software package developed by Dow-Key using National Instruments Lab-View. The key component of this test solution is the 2 x 32 Switch Matrix. This unit has an integrated, Window-based computer that performs a double function; internal control of the switch matrix and control of the whole test process, including data acquisition. The Switch Matrix is equipped with a Windows-based operating system, LCD TFT Monitor, and a Touch Screen with a user friendly GUI.

The DUT is one of the latest Switch Matrices introduced by Dow-Key over the last few months. This family of RF Switching Matrices includes both solid state and electromechanical designs. It has been developed to meet very demanding RF specifications. These designs cover the most common frequency ranges: 2 – 32 MHz, 20 – 200 MHz, 20 — 1100 MHz, 800 -2500 MHz, and 1 —1. They also meet the most demanding specifications for RF signal routing systems.

Dow-Key”s product line of switches range from single-pole single-throw to single-pole 14-throw as well as transfer, inline, waveguide, switch matrices, and integrated modular switch assemblies.
