Working Principle

The SKY12211-478LF is controlled by an external voltage or current source. It works in tandem with a switched capacitor array which is responsible for providing the switch\'s low power consumption. When a voltage is applied, the switch is closed, and when the voltage is removed, the switch is open. Additionally, the voltage applied can also be used to control the switch\'s insertion loss, return loss, and isolation.

The capacitor array allows for extremely low power consumption and results in minimal heat generation. Furthermore, the application of the correct voltage provides excellent RF isolation in the circuit.

Conclusion

The SKY12211-478LF is a high-performance RF switch that is designed for use in a variety of applications. With its low power consumption, low insertion loss, excellent linearity, and high port-to-port isolation, it is ideally suited for those applications where space and/or power are a concern. Additionally, its input and output signals are fully shielded, allowing for low interference and cross talk between neighbouring parts of the same circuit. Finally, its working principle is based on a switched capacitor array which results in low power consumption and minimal heat generation.
