In accordance with an embodiment, a filter network is configured to be coupled to a first switch, a second switch, and an output port. The filter network includes a first filter coupled between the first switch and the output port, and the second filter coupled between the second switch and the output port. The first filter has a pass band having a first frequency range that includes a first frequency, and a stop band that includes a second frequency that is a distortion product of the first frequency. The second filter has a second frequency range that includes the second frequency and the stop band that includes the first frequency. The second frequency range is higher in frequency than the first frequency range. |

1. A filter network configured to be coupled to a first switch, a second switch and an output port, the filter network comprising:
a first parallel LC circuit directly connected between the first switch and the output port, the first parallel LC circuit having a pass band comprising a first frequency range that includes a first frequency, and a first stop band comprising a second frequency, the second frequency being a distortion product of the first frequency, wherein the first parallel LC circuit has a notch at the second frequency; and a second parallel LC circuit directly connected between the second switch and the output port, the second parallel LC circuit having a pass band comprising a second frequency range that includes the second frequency, and a second stop band comprising the first frequency, wherein the second frequency range is higher in frequency than the first frequency range, and the second parallel LC circuit has a notch at the first frequency. |
