Research summary

Future cellular handsets will be required to support numerous radio access technologies, using a variety of duplexing modes over a wide range of operating frequencies. In today's Radio Frequency front-ends, multi-band frequency division duplex (FDD) operation is achieved using a separate off chip filter for each supported band. Supporting the >30 FDD bands defined in the LTE (4G) specification would lead to a prohibitively large, expensive and lossy architecture, and because of this today’s smartphones only support a subset of these bands. Different devices are manufactured for different global regions depending on regional frequency usage, increasing manufacturing costs, preventing ...
