Our commitment to continuous improvement initiatives within our products and processes, along with the extensive series of internal and external assessments, ensures compliance in accordance with the AS9100 and ISO-9001:2000 standards requirement, which facilitates the registration process and continued certification in order to secure Dow-Key s future as a primary source for advanced RF switching products. 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).
