The evolution of LTE smartphones is currently being accelerated to include the function of multiband support, which uses more than one frequency band to support high-speed communication. There have been an increasing number of smartphone models that can be adapted for carrier aggregation, or CA, as well. The configuration of RF front end has become increasingly complex, which has made it hard for makers to provide terminals with ideal characteristics desired by clients within a short lead time. To provide solutions for this kind of problem, Murata has engaged itself in the development of PAMid, an integrated RF front end module, taking advantage of self-manufactured RF front end.
