N-Plexer and N-Band acoustic filters based on transversal configuration

This work shows the feasibility of using filters with transversal configuration to create N-Plexers and N-Band responses, by directly connecting several BAW filters in a transversal manner. The new multi-filtering solutions might indeed help on the existing and forthcoming challenges for LTE or 5G, such as the efficient management of the limited spectrum allocation or the non-contiguous spectrum, with the aim of increasing the network capacity and higher data rates. The filter arrangement proposed shows as well flexibility on dynamic scenarios like the ones occurring in a Carrier Aggregation (CA) access [1].
