High frequency (RF) relays are devices that can be used to control the state of high-frequency signals or transfer signals between two circuits. They are typically used in telecommunication switches, radio systems, and computer communication networks. The 9402-12-20 high frequency relay is an example of these essential components, used in a variety of applications and possessing a wide range of capabilities.

A 9402-12-20 high frequency relay consists of two main parts: an actuator module and a relay contact module. The actuator module is the control element responsible for raising and lowering the relay contact, allowing a signal to either pass through or be cut off. It is also responsible for controlling the current flow across the relay contact points. The relay contacts, on the other hand, are responsible for connecting and disconnecting high frequency signals that are carried on conductive wires or several antennas.

The 9402-12-20 relay is a coil type switch. An energizing coil is used to move the internal contact form one position to another. The current is send through the coil for a certain period of time, which creates an electromagnetic force that causes a plunger to operate the contacts within the switch. This type of relay is typically used for high frequency, radio frequency, microwave signal transmission, and signal amplification applications.

The 9402-12-20 high frequency relay has many unique advantages. For one, it has low insertion loss, meaning that the contact between the relay contact and the circuit is able to pass signals with minimal power loss. It is also able to fulfill high loads, being able to transfer 5A or more with some versions. Other important specs include good isolation, frequency response from DC up to 18GHz, low control power, 90dB attenuation, and tight control range of 0-6V.

The 9402-12-20 high frequency relay is used in a wide variety of applications. One of the most important uses is in telecommunications switches, where it is used to switch and control the state of audio signals. Due to its excellent insertion loss and high load-carrying capabilities, it is also used in radio systems to amplify signals or transfer them between different circuits. This type of relay can also be used in computer communication networks as a switching device to transfer data between multiple circuits.

The 9402-12-20 high frequency relay is an example of the essential components used in the field of RF and microwave engineering. Its wide range of capabilities, from good isolation and high current carrying capacities to its low control power and tight control range, make this relay ideal for a variety of applications.
