SINGLE RECEIVER INTRA-BAND NON-CONTIGUOUS CARRIER AGGREGATION

摘要

A single receiver to process multiple signals to achieve carrier aggregation includes a main path, an auxiliary path and one or more local oscillators. The main path has an input that receives an input signal. The input signal includes non-contiguous wanted signals and a jammer signal. The single receiver also includes an output coupled to a modem. The output provides the wanted signals to the modem. The auxiliary path is coupled to ground and includes an N-path filter. The N-path filter has multiple mixers. The N-path filter filters out at least a portion of the jammer signal in one or more gaps between the non-contiguous wanted signals in a same frequency band. The one or more local oscillators are coupled to the main path and/or the auxiliary path to provide a first reference signal to the main path and/or to the N-path filter of the auxiliary path.
