Dow-Key Microwave heavily focuses on providing the best and most reliable switching systems to the ATE industry and we have been successful in our mission since 1999. In automated test systems, the critical role switching segment plays in the overall testing is often overlooked and taken for granted. The performance of a test system is only as good the switches routing the signal, even with the most sophisticated test instruments.

We take pride in our ATE switch solutions to allow the user to test the UUT /DUT (unit under test / device under test) without worrying about the switching segment. We will take care of it for you. Our ATE solutions are available from DC up to 40 GHz and are offered with various software interfaces with minimum effort required to control the switch matrices.

Features and Capabilities:
Our matrices consist of building blocks:
  • 1U/3U/4U/6U chassis or larger
  • LCD/keypad or touch screen local control interface
  • Expandability by cascading specific units using CANbus and with master/slave control capability
  • Ethernet, RS-232, GPIB, EWEB (website interface), LNET (LXI) or SNMP remote control interfaces
  • Dow-Key SCPI commands which can easily be embedded into test scripts.
  • LabView Graphical User Interface (GUI) for visual representation of port settings and status check.
  • Power combiners/dividers for fan-in/fan-out matrices
  • Amplifiers and other passive components may be used on design basis.

Dow-Key Microwave has been at the forefront of RF switch technology for decades and has long been the leader in efficient electromechanical matrix design and development. Current Dow-Key RF technology integrates a Next Generation Matrix Platform; a flexible, yet modular system architecture comprised of a series of brackets, panels and electronic-boards that are universal among all Dow-Key electromechanical models.

Our MS- series consists of multiple switches being mounted on the rear panel and can be reconfigured with SPDT (by terminating one DPDT port to 1x2), transfer DPDT (2x2), SP6T (1x6) and SP10T (1x10) switches. We can populate any number of CANbus switches in 19" rack chassis and mix the type of switches per customer need. To learn more, download our Electromechanical Matrix products.

Our multiplexer switch matrices offer the user the capability to route one input to as many as 100 outputs (it is bidirectional) or more if using SP12T switches. It is offered with operating frequencies up to 18 GHz, 26.5 GHz and 40 GHz depending on the type of configuration needed. To learn more, download our Electromechanical Matrix products.

Dow-Key understands the need of switching between more complex test setups may be required. Therefore, our CB-series crossbar matrices are an excellent choice that allows the engineer to test multiple UUT without having to connect and disconnect them from the test setup. A crossbar matrix allows the user to switch an input signal to any output port at a time. The CB-series offer systems up to 12 inputs and 12 outputs with an operating frequency up to 26.5 GHz (for most configurations). To learn more, download our Electromechanical Matrix products.
