Abstract

RF communications circuitry, which includes a first tunable RF filter and a second tunable RF filter, is disclosed. The first tunable RF filter is coupled to the second tunable RF filter. The RF communications circuitry operates in one of a first operating mode and a second operating mode. During the first operating mode, the second tunable RF filter receives and filters an upstream RF signal to provide a filtered RF signal. Further, during the first operating mode, the first tunable RF filter augments a frequency response of the second tunable RF filter.
