High Frequency (RF) Relays are electronic switches used to isolate, buffer or amplify signals in the radio frequency (RF) range. In this range, signals move at frequencies ranging from 300 MHz to 3 GHz, with operating voltages from 0-12 Volts. These relays are often used in mobile wireless applications, navigation systems and high-speed data communications. The RF relays are designed to provide maximum signal integrity, hence they are widely used in applications where noise rejection and disturbance immunity is critical.The 2920-05-121 RF relay is an electromechanical, open-frame relay. It is designed to switch between two states, normally open and normally closed, under the application of RF power. The maximum Voltage Standing Wave Ratio (VSWR) it can handle is 2.2:1 over the frequency range of 900MHz–2GHz. The relay has an operational temperature range of -40°C to +85°C, and can switch RF power up to 1A and 100V max.The 2920-05-121 RF relay is a perfect solution for applications requiring low power switching, like wireless antenna polarisation, cellular base-stations, stealth aircraft installations etc. This type of relay is also ideal for antenna diversity, which is a widely used application in modern wireless communication.The operation of the 2920-05-121 RF relay is quite simple. It works on the principle of magnetic field produced by an electromagnet. When a voltage is applied to the coil, the electromagnet produces a magnetic field, which attracts the armature. This, in turn, closes the contact to form a connection between two circuits. When the power is removed from the coil, the armature is pulled back to its original state, thus breaking the connection and allowing the contacts to open. This process is repeated every time the power is applied or removed from the coil.In summary, the 2920-05-121 RF relay is designed to switch between two states, normally open and normally closed, under the application of RF power. Its maximum VSWR, 2.2:1, makes it ideal for use in applications requiring low power switching, like wireless antenna polarisation, cellular base-stations, stealth aircraft installations etc. It works based on the principle of magnetic field produced by an electromagnet, which is activated when a voltage is applied to its coil.
