1. A carrier aggregation (CA) multi-path radio-frequency (RF) adaptive tuning network switch architecture, including:
(a) a multi-path switch having a plurality of signal ports and a common port, the multi-path switch configured to concurrently connect at least two selected signal ports to the common port in at least one CA mode of operation;
(b) a plurality of band filters, each corresponding to an associated RF frequency band; and
(c) at least one filter tuning block coupled between an associated signal port of the multi-path switch and at least one associated band filter, each filter tuning block configured to adjust the RF characteristics of its associated band filter with respect to at least one other band filter when operating in at least one CA mode of operation so as to suppress a loading effect for at least one other band filter.
