What is a High frequency relay?

A high-frequency relay is one of the elements that switch high-frequency signals. Since high-frequency relays generally do not have connectors, they are used by soldering, and high-frequency characteristics are greatly affected by the substrate. Also, when relays are used in high-frequency circuits, there are problems of isolation (signal leakage between contacts (between circuits) when the contacts are open) and insertion loss (signal loss when the contacts are closed).

Application of High frequency relay

１．Wireless Communication: High-frequency relays are used in wireless communication devices to switch and transmit signals, playing a crucial role in wireless transmitters and receivers.
２．Testing Equipment: High-frequency relays are employed in electronic testing equipment to switch various frequency signals, aiding in the performance evaluation of devices.
３．RFID Systems: High-frequency relays are used to control communication between RFID readers and tags, enabling efficient data exchange.
