ARXP1109 Application Field and Working PrincipleHigh Frequency (RF) Relays belong to the class of electromagnetic relays, which rely on the action of a magnetic field to open or close one or more electrical contacts. They are built with a coil and contacts mounted on a single circuit board. The coil is typically connected to an external power supply and when energized, creates a magnetic field that actuates the contacts. RF relays are often used in telecommunications and broadcast equipment due to their high switching speed, good isolation properties, and high signal fidelity.The ARXP1109 is a high-frequency relay manufactured by Molex Corporation, a leading provider of high quality connectors and other electronic components. It is designed to operate at frequencies up to 18 GHz. It has an exceptionally low insertion loss of 0.2 dB and a high isolation of 53 dB, making it ideal for applications such as amplifier protection and signal routing in radio and microwave equipment. The ARXP1109 consists of two essential components: the main switch module and the bias switch module. The main switch module contains the primary winding and two transfer contacts. When the primary winding is energized with RF signals, a magnetic field is generated around the contacts, causing them to move towards each other and close the circuit. The bias switch module contains a secondary winding and two actuating coils. When the secondary winding is energized, a secondary magnetic field is generated which causes the actuating coils to move away from each other, opening the circuit and protecting the contacts against damage due to excessive current. The ARXP1109’s design is optimized for high frequency applications, providing excellent signal fidelity and low insertion loss. It can be used to switch signals up to 18 GHz, making it suitable for applications such as amplifier protection, signal routing in radio and microwave equipment, and general switching applications. It is suitable for both ac and dc applications and is capable of switching currents up to 16 A and voltages as high as 24 V. It is also resistant to shock and vibration, making it suitable for use in harsh environments.In summary, the ARXP1109 is a high frequency (RF) relay that is ideal for applications such as amplifier protection, signal routing in radio and microwave equipment, and general switching applications. It is designed to operate up to 18 GHz with low insertion loss and high isolation, making it suitable for use in harsh environments. It is designed to switch currents up to 16 A and voltages as high as 24 V, and is resistant to shock and vibration.
