OUR EXPERIENCE, YOUR SWITCH SOLUTION SINCE 1945

EXPERIENCE.Custom designs and hundreds of standard units supporting the aerospace, military, transportation, and communications

industries for signal routing and ATE applications.

Dow-Key Microwave, a leader in design and manufacture of switching products, acquired its matrix product line from K&L Microwave (our sister company and part of Ceramic & Microwave Products group) in 1999. Over a decade later, Dow-Key has expanded its line vigorously to meet the needs of today’s customers and has offered over 150 custom designs and hundreds of standard units supporting the aerospace, naval, transportation, military, and communication industries with signal switching applications.

Features and Capabilities:The majority of our matrices consists of building blocks:

1U/3U/4U/6U chassis (other sizes are available)•LCD/keypad or touch screen local control interface•Ethernet/RS-232, GPIB/RS-232, EWEB (web browser), LNET (LXI) or SNMP remote control interfaces.•Expandability by cascading specific units using CANbus and with master/slave control capability•Dow-Key SCPI commands•LabVIEW Graphical User Interface (GUI)•Power combiners/dividers for fan-in/fan-out matrices•Amplifiers and other passive components may be used on design basis.•

Matrix models and solutions are classified with different types of switch configurations:

Switches: The matrix is populated with individual RF switches (DPT, SP6T, …, SP12T) and are not combined in

any other ways.

Blocking: Switches are combined in ways where some RF paths are blocked.

Crossbar (non-blocking): Any input can be connected to any output one at a time (1 input to 1 output).

Fan-Out (non-blocking): Each input fans out to all outputs such that any input can be connected to one or multiple

outputs simultaneously (1 input to many outputs).

Fan-In (non-blocking): All inputs are combined (fan-in) into each output, thus allowing one or multiple inputs to be

connected to any output simultaneously (many inputs to 1 output).

Engineering TeamThe best in the RF switch industry, Dow-Key’s engineering team is dedicated to support customers all the way from product selection, custom solution design to RF system integration and post production support. Team members who have been with Dow-Key prior to the establishment of this product line are still with Dow-Key and such experience is priceless. It allows us to provide customized solutions built per customer’s specs to meet all types of signal switching needs. Backed by decades of industry experience, our highly skilled technical staff is continuously improving the quality and variety of our product offering to meet the needs imposed by the RF industry.

PXI Switching Modules – Reconfigurable Modular SolutionsThe PXI family offers three modules with different RF coaxial switch configurations: Dual SPDT, DPDT, SP3T, SP4T, SP6T, 4x4 or 2x5. Depending on the model, the PXI solutions operate either between DC -18 GHz or between DC - 26.5 GHz. Model 12K3S offers the user the flexibility to combine up to three different switches in one single model and by removing external RF cables on Model 14F32-1/4x4, the user can reconfigure the unit to terminated (e.g. SPDT or SP3T) switches.

Additional HardwareNational Instrument PXI chassis (PXI-1036 or similar) is required.

SoftwareEach switch can be controlled via Dow-Key LabVIEW, LabWindows, or Visual Basic Graphical User Interface. Also, the modules are VISA and IVI compatible and no additional drivers are needed.
