High Frequency (RF) Relays are a type of electromechanical switches used to control high frequency circuits and enable users to switch RF signals on and off with minimal or no deterioration of signal quality. The 9402-12-30 range of RF Relays has been developed to provide a wide range of options for customers needing a high-reliability, low-cost radio frequency switching solution for their applications.

9402-12-30 Application Field

The 9402-12-30 relays are typically used in the following applications:

• Broadband Communications
• Wireless Telecoms
• Satellite Telecommunications
• Avionics
• Industrial Automation and Control
• Medical Diagnostics and Monitoring
• Radio Frequency Identification Systems (RFID)

It can also be used in any application where a high-performance, reliable RF signal switching device is required.

9402-12-30 Working Principle

The 9402-12-30 relay consists of two independent solenoids placed within a single housing and a common switching contact for both solenoids. The relays operate by creating a magnetic field in the coil of the solenoid when an RF signal is applied. This magnetic field acts upon the armature inside the solenoid to move the armature to the closed contact position and activate the switching contact. When the RF signal is turned off, the magnetic field dissipates and the armature moves back to the open contact position.

The relay has a good On/Off ratio as well as a fast response time. It also has a high-frequency self-resonant frequency and is immune to spurious signals at any frequency within its operating range.

The 9402-12-30 relay has a low insertion loss and provides excellent repeatability, thereby enabling reliable switching of RF signals. The relay also has a low power consumption, making it a very power-efficient solution.

Conclusion

The 9402-12-30 range of RF Relays is an excellent choice for applications requiring reliable switching of RF signals. With its fast response time, low power consumption, and high-frequency self-resonant frequency, the 9402-12-30 relay provides a reliable and power-efficient RF signal switching solution.
