Power Handling Capability of Electromechanical Switches
●Introduction
■RF/microwave electromechanical switches are used in a wide variety of signal routing applications for test and measurement systems. Typical applications for electromechanical switches include: selection of multiple signal sources to one output, selection of multiple input signals to one measurement instrument, transfer switching to insert or remove a device in a signal path and matrix switching of multiple inputs and outputs. Keysight Technologies, Inc. electro-mechanical switches provide broadband performance with low insertion loss, high isolation, and exceptional repeatability throughout a long operating life. One important parameter for electromechanical switches that is often misunderstood is power handling. The ability of a switch to handle power is very dependant on the design and materials used in a switch. In the data sheet, there are different power-handling ratings for the switches such as hot switching, cold switching, average power and peak power. Understanding these different terms will help you avoid catastrophic failure of the switch or instruments.
