Recent Developments in Integrated Interferer-Tolerant Receivers for Reconfigurable Radios

Fragmented spectrum allocations at RF and mm-Wave, increased use of carrier aggregation/MIMO dense spectrum-reuse in wireless links has led to interest the design integrated wideband, high-linearity MIMO RX that provide low noise, blocker tolerance reconfigurability across signal domains. In this paper, receive architectures for wide operating range are presented with a focus on recent developments reconfigurable N-path receivers. Generalized sequence-mixing support frequency/spatial/code-domain rejection filtering described along directions research extending operation wider bandwidths higher frequencies.
