Description
Book SynopsisRF-MEMS, or MEMS with radio-frequency functionality, were originally developed in the 1990s. Their characteristics in terms of low loss, high isolation and wide tunability were outstanding when compared both to standard RF/microwave components and to semiconductors. Such remarkable performance led many to expect a large adoption of RF-MEMS components in mass-market applications, especially mobile devices and handsets. This revolution was ultimately not realised. However, over the last few years, RF-MEMS have started to make their way into the market landscape, thanks to a need that other technologies were unable to address as effectively.
With the advent of modern 4th-generation (4G) smartphones, adaptive impedance tuners are now the first successful example of exploitation of RF-MEMS technology in the consumer market, and ahead of us lies the 5th-generation (5G) of mobile communications and services. 5G will demand an increase in data volume by a factor of 1000, as well
