Abstract

Front-end systems with an adjustable filter architecture are provided. In certain embodiments, a front-end system includes a first bandpass filter with a first passband, a second bandpass filter with a second passband, a stopband filter with a stopband, and switches for controlling connectivity of the filters along transmit and receive paths. The first passband and the second passband include a frequency overlap region, which the stopband at least partially overlaps. The re-configurability of the switches allows for the overall filtering characteristic of the adjustable filter to adjust the duplex gap between transmit and receive passband edges, as well as the passband edges themselves.
