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.

Facility Dow-Key s state-of-the-art facility presently consists of a single building totaling 36,000 square feet. To accomplish design, manufacture, and test of Dow-Key products and assemblies, we invest heavily in capital equipment such as vector network analyzers and synthesized sources, phase noise test sets, noise figure measuring equipment, passive inter-modulation (PIM) test setups, thermal vacuum chambers, RF power meter, shock and vibration station for environmental screening. In addition, we house two Class 7 clean rooms to support our high reliability space and military projects. 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).
