3G – 4G – 5G: How Baw Filter Technology Enables a Connected World

Abstract

5G is highly anticipated by service providers, phone manufacturers and consumers. 5G marks a dramatic increase in data rates. The number of frequency bands requiring high performance filters increases significantly. BAW is particularly well suited for new bands below 6 GHz, many of which have very wide bandwidth and close-by neighbors. The only path forward to achieve full connectivity in LTE 4G + 5G wireless is RF integration; complexity of the antenna systems and the resulting coexistence challenges will dictate it. The article discusses trends for BAW, wide bandwidth and miniaturization.
