Abstract:
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.
