High Frequency (RF) relays are widely used in various application fields where precise electromagnetic and mechanical switching between two ports is required. The ARJ22A03 is a unique RF relay designed for applications where two ports operate at RF frequencies up to 22 GHz. Its advanced construction and components make it ideal for applications requiring reliable high frequency switching.

The ARJ22A03 is a two-pole RF relay with a mechanical switch contact design that allows for low signal loss and high isolation between ports. The relay can be utilized in both switched and linear control configurations, providing a very versatile solution for high frequency switching needs. The relay has extremely fast switching time which is as low as 5μs and is constructed using Nylon-6 polymer materials for reliable operation in high temperature environments.

The working principle of the ARJ22A03 is based on the pin diode switching technique. The two contacts of the relay are opened and closed by an electromagnet that is operated by an externally applied DC voltage. When the DC voltage is applied, the magnetic field created attracts the switching diode, which in turn closes the relay contact, thereby enabling electrical connection between the two ports. The magnitude of the current passing through the relay is controlled by the current regulating diode present in the switch.

The ARJ22A03 is suitable for a wide range of applications including base station antenna switching, cell splitters, filter switching, linear attenuators, and RF test equipment. It has a high power handling capacity of up to 100 W and excellent linearity that ensures negligible signal distortion. The relay is also very robust and reliable with a long lifetime and low insertion loss.

The ARJ22A03 is capable of operating at up to 22GHz frequency and can maintain its electrical performance over a wide temperature range. Its small size and low power requirements make it ideal for applications where space and energy are critical. The product is also compliant with RoHS and REACH standards and consumes less than 0.1W of power. All these features make it an ideal solution for a wide range of high frequency switching applications.
