I have a switchable capacitor. the ON/OFF ratio is 20:1. It can work under high microwave power 36dBm, at 4-10GHz. The loss in ON is 0.6dB, in OFF state is -25dB. At lower than 4GHz, the insertion loss is higher.
Do you have any idea on the application of this device? Any circuit only have microwave component and doesn't need DC component?
