What are RF Surge Protectors and Arrestors?
Electric Surge is a momentary disturbance/spike in current, voltage or power in an electric circuit. This electric surge which is usually caused by lightning or some other external factor can damage the device under operation, if not appropriately managed.
An RF surge protector or arrestor is used to protect various wireless components or systems. The arrestor limits the amount of voltage supplied to an electronic device by suppressing or reducing the current to the threshold level of the device. Surge Protectors improve the reliability of the wireless network by guarding it against sudden changes in the voltage due to lightning strikes.
The transient changes in the voltage arise in the form of spikes, which could be more than 1000 volts. The voltage spikes are generated when lighting hits the power line. Such high voltage spikes can damage the sensitive components in an electronic device. The wireless components in the receive chain of a system are very sensitive to electrical signals as they are designed to receive very low signals transimitted to them from various mobile/wireless devices.
When selecting a surge protector you need to specify the frequency, connector type, max voltage/current that you need the device to protect against and other parameters. There are a number of RF surge protector types, each type is created using a different set of technologies. The main arrestor types are Gas Discharge Tube, Filters, Avalanche Diode, Quarter-Wave Shorting Stub (QWS) etc.
everything RF has listed RF Surge protectors from the leading manufacturers. Use the filter tools to narrow down on the list of products from the leading manufacturers. Once you find products that match your requirement, you can view product specification, download datasheets or request a quotation. Quotation requests are sent to the manufacturers and their distributors in your region who then get back to you with the requested information.
