RF switches

RF switches are active components used to control the flow of electrical signals in the radio frequency (RF) domain. As their name suggests, they are used to switch RF signals from one place to another and are often used in radio communications, wireless systems, and in satellite communications.

NJG1528KC1-TE3# is an RF switch that provides low reflection, low insertion loss, and high isolation. It is an ideal candidate for RF signal routing in broadband applications.

Application Field

NJG1528KC1-TE3# is most often used in cellular and mobile networks where the signal routing needs to be efficient and precise. It is also used in combination with other components like antennas, mixers, and other circuitry to enhance the signal purpose. Additionally, it can be used with RF test equipment and cellular radio handsets.

Working Principle

NJG1528KC1-TE3# is basically an electromechanical switch that controls the flow of current through its terminals and is usually controlled via an external voltage. The switching action is usually achieved by the movement of a membrane and springs over a set of contacts. This creates a seal between the contacts, thereby collimating the signal and ensuring minimal loss.

Since the unit does not actually amplify or modify the signal in any way, its power handling capabilities are dependent on the contacts and the switching elements. It has a high isolation of over 30 dB and low residual leakage of better than -65 dB.

NJG1528KC1-TE3# is designed for operation in a wide range of temperatures and offers high linearity and virtually no transient distortions. Its low pass filters help reduce out-of-band noise, while its low RF reflection helps optimize performance. The unit is also capable of handling up to 0.5W of power at frequencies up to 3 GHz.
