Super Components and Assemblies

Ventura, California – March, 2004

Dow-Key Microwave has the capability to design additional functionality into basic switches, or procured components, thereby creating what we call “super components.” We incorporate these “super components” into the design and manufacture of large subsystems, providing an opportunity to adjust and optimize individual component performance as well as interface performance. Overall peformance of our subsystems has proved to be far superior when compared to assemblies of components purchased from various component suppliers.

The SP12T Switch with CANBus and/or Ethernet Interface has additional sets of contacts and SMA connectors. By installing 50 ohm terminations directly on the extra SMA connectors, a switch configuration with internal terminations is created. High power terminations can also be mounted remotely and connected by an RF cable to the termination port.

The 2 x 5 Switch Matrix is a self-contained unit with no RF cables required. This highly integrated unit is 4.3 x 2.6 x 1.75″ with a maximum weight at 500 grams. It offers a perfect solution for applications where size and weight are critical. RF performance is excellent at 18 GHz; insertion loss is less than 0.7 dB, and isolation is 60 dB minimum

The 4 x 4 Non Blocking Switch Matrix with CANBus Interface performs from DC to 18 GHz. This product can also be equipped with the Ethernet Interface EWAB version that can be easily accessed from anywhere in the world via TCP/IP protocols on 10Base-T networks using HTTP 1.0 interface.

This Switch Isolator is an example of how Dow-Key switches can be combined with other components to achieve overall superior performance. Components that can be designed into “super components” include isolators, filters, low noise amplifiers, couplers, and others. There are infinite possibilities.

Complete Switch Matrices with complex RF Interfaces for signal routing applications are designed and manufactured by Dow-Key Microwave. This extensive product line includes matrices based on electromechanical switches as well as solid state switches. These matrices utilize numerous passive components to customize thesignal and amplifiers to compensate for losses from RF components and cables.
