High Frequency (RF) Relays

RF or microwave relays are electronic switching devices specifically designed to transmit and receive ultra-high frequencies. Many applications require the relaying of data at speeds that exceed the maximum speed of a traditional DC relay. RF technology has the ability to provide signal switching without significantly degrading the data, and this has led to the development of RF relays. RF relays are versatile switches that can be adapted for many applications including digital communications, military, or other industrial applications.

9903-05-10: Technology and Working Principle

The 9903-05-10 RF relay is a miniature, single-pole, normally-open (SPNO) contact high frequency switching relay designed to switch nominal frequencies of up to 3000 MHz (3 GHz). It is well suited for digital communication applications, as it works to open and close its contacts without power, avoiding the risk of overloading the power source and interrupting communication. Further, its contacts can handle voltages up to 6.5Vdc and currents up to 10A with minimal loss. This relay is also hermetically sealed and, as a result, provides excellent electro-magnetic interference (EMI) and radio-frequency interference (RFI) protection.At the core of the relay is a movable armature. When the coil of the relay is energized, the armature is drawn up, causing the contacts to open and disconnecting the power supply. This, in turn, causes the relay contacts to close, allowing the current to flow. When the current is not present, the armature moves back to its original position, opening the contacts and breaking the power flow.

Applications

The 9903-05-10 RF relay is well suited for high speed signal switching applications. One example is its use in digital communications, where it can be used to switch a data signal from one location to another without any loss of signal integrity. In addition, RF relays are frequently used in military applications, where they are used to switch signals between transmitters and receivers or between multiple antennas.The 9903-05-10 RF relay is also often used in industrial applications, such as remote monitoring applications, automated test systems, and radiation protection systems. The switch configuration of the relay makes it particularly useful in applications where a high-speed switching action is required.

Conclusion

The 9903-05-10 RF relay is a versatile, high-frequency switching device that is ideal for applications that require high-speed switching at extreme frequencies. It is well suited for applications where the signal integrity must be maintained, and it offers excellent EMI and RFI protection. Its hermetically sealed design ensures that the relay will function with minimal power and no interruption of the power source. The 9903-05-10 RF relay is a reliable and robust switching solution for many applications.
