  • An RF switch matrix is an array of RF switches arranged to route radio frequency (RF) signals between multiple inputs and multiple outputs. Applications requiring RF matrices include ground systems, test equipment, and communication systems. An RF matrix is used in test systems, in both design verification and manufacturing test, to route high frequency signals between the device under test (DUT) and the test and measurement equipment. In addition to signal routing, the RF/Microwave Switch Matrix may also contain signal conditioning components including passive signal conditioning devices, such as attenuators, filters, and directional couplers, as well as active signal conditioning, such as amplification and frequency converters. Since the signal routing and signal conditioning needs of a test system differ from design to design, RF/Microwave Switch Matrices may be custom designed by the test system engineer or by a hired contractor for each new test system. The Switch Matrix is made up of discrete electronic components including RF switches and signal conditioners that are mounted together in a mechanical infrastructure or housing. Cables interconnect the switches and signal conditioners. The switch matrix employs a driver circuit and power supply to power and drive the switches and signal conditioners. The switch matrix uses connectors or fixtures to route signals from the sourcing and measurement equipment to the DUT. The switch matrix is typically located close to the DUT to shorten the signal paths, thus reducing insertion loss and signal degradation. (en)
