Description
In recent years, requirements for antenna selective combiners used in base stations for mobile communications have been hardened two-fold as follows: on the one hand, selectivity and insertion loss have become more and more stringent, on the other hand the complexity (in terms of number of filters, ports and number of pass-bands) of such devices has increased beyond the typical duplexer structure. To cope with this, a number of new filter-based antenna combiners have emerged. In this talk, various solutions for such devices will be discussed both from the synthesis and implementation points of view.
