WSC: Advances in PA and TX architectures

Although most PA and TX architectures (Doherty, Polar, outphasing, LINC, …) have been envisioned several decades ago, there is not a clear winner today. Technology considerations (GaN, CMOS, SiGe,…), system level considerations (output power, bandwidth,…), implementation and packaging issues and the specific cost or business model (basestations, terminals,…), make the optimal choice less obvious. This workshop will cover the different solutions that exist today for PA and TX architectures. It will discuss the different trade-offs and implementation issues of the various architectures, crucial information when selecting the architecture of choice. All speakers will also give an outlook of new PA architectures that are being developed in their field.
