Methods and system for using a multifunctional filter to minimize insertion loss in a multimode communications system are described. Specifically described is a multifunctional filter that is configurable to operate in a bandpass mode when a first type of signal is propagated through the multifunctional filter, and to operate in a lowpass mode when a second type of signal is propagated through the multifunctional filter. The multifunctional filter presents a lower insertion loss to the second type of signal when operating in the lowpass mode than in the bandpass mode. |
