用于射频开关的系统和方法
摘要：
本发明涉及用于射频开关的系统和方法。根据实施例，一种电路包括：在相应的多个RF端口和公共RF端口之间耦合的多个开关网络，以及控制电路。多个开关网络中的每一个包括在其相应的RF端口和公共RF端口之间耦合的第一开关，并且多个开关网络中的至少一个包括在第一开关和公共RF端口之间耦合的可选择的网络，使得可选择的网络提供处于第一状态的DC路径和处于第二状态的串联电容。
摘要（英）：

In accordance with an embodiment, a circuit includes a plurality of switching networks coupled between a corresponding plurality of RF ports and a common RF port, and a control circuit. Each of the plurality of switching networks includes a first switch coupled between its corresponding RF port and the common RF port, and at least one of the plurality of switching networks includes a selectable network coupled between the first switch and the common RF port, such that the selectable network provides a DC path in a first state and a series capacitance in a second state.
