摘要：
A band switch with a switchable notch for receive carrier aggregation is disclosed. The band switch has at least one input and an output with at least one series switch coupled between the at least one input and the output. The at least one series switch is adapted to selectively couple the input to the output in response to a first control signal. The band switch also includes at least one shunt switch coupled between the at least one input and a voltage node. The at least one shunt switch is adapted to selectively couple the at least one input to the voltage node in response to a second control signal. In addition, at least one notch filter is selectively coupled to the output in a shunt configuration, wherein the at least one notch filter is configured to attenuate signals within a stop band to attenuate harmonics and distortion.
