High Frequency / RF Relays

High-frequency/RF relays are electronic switches designed to operate at a wide range of radio frequencies and power levels. These relays are used in many applications, such as high-frequency RF switching, RF front-end control and protection, and in instrumentation applications, to control and isolate RF signals. The construction of an RF relay is slightly different from that of a regular switch. A typical relay consists of a coil, two contacts, and an armature. The contacts are typically made from materials such as gold or silver, as these materials are capable of handling large electrical currents without corrosion. The coil is connected to a voltage source, which when energized creates an electromagnetic field that moves the armature to bridge the two contacts. This creates a closed circuit and allows an electrical current to flow. When the voltage is removed, the armature moves back to the open position and the circuit is broken. In addition to performing the basic switch function, the RF relay also has added features such as RF filtering and shielding. They are designed to be very reliable and can handle power levels up to thousands of watts.
