摘要： A circuit includes multiple switching networks coupled between corresponding multiple RF ports and a common RF port. Each of the multiple switching networks includes a first switch between its corresponding RF port and the common RF port. At least one of the multiple switching networks includes a selectable network between the first switch and the common RF port. The selectable network provides a DC path in a first state and a series capacitance in a second state. A control circuit is configured to establish an RF path by activating a first switch and by deactivating other first switches. The control circuit is also configured to establish an RF path by placing a selectable network in the first state when the control circuit operates in a first mode and by placing a selectable network in the second state when the control circuit operates in a second mode.
