Abstract:
1. A method of minimizing insertion loss in at least one of two types of signals propagated through a communications system, the method comprising: configuring a configurable combination filter to operate in a band-pass mode when a first type of signal is propagated through the combination filter, the combination filter comprising a plurality of independently selectable serial filter components, a plurality of independently selectable shunt filter components, a plurality of parallel switches connected in parallel with the plurality of independently selectable serial filter components and a plurality of serial switches connected in serial with the plurality of independently selectable shunt filter components, and wherein configuring the combination filter to operate in the band-pass mode comprises providing a first propagation path of the first type of signal by including the plurality of independently selectable serial and shunt filter components in the first propagation path, wherein the including comprises placing the plurality of parallel switches in an open position such that no serial switch is present in the first propagation paths and placing the plurality of serial switches in a closed position; and configuring the combination filter to operate in a low-pass mode when a second type of signal is propagated through the combination filter, wherein configuring the combination filter to operate in the low-pass mode comprises providing a second propagation path of the second type of signal by removing at least one filter component of the plurality of independently selectable serial and shunt filter components from the second propagation path by placing a corresponding parallel switch of the plurality of parallel switches in a closed position or by placing a corresponding serial switch of the plurality of serial switches in an open position, the low-pass mode providing a lower insertion loss upon the second type of signal than the band-pass mode.
