The baseband processors and radio transceivers in all modern wireless networking devices and mobile phones are mass-produced using RF CMOS devices. RF CMOS circuits are widely used to transmit and receive wireless signals, in a variety of applications, such as satellite technology (such as GPS), bluetooth, Wi-Fi, near-field communication (NFC), mobile networks (such as 3G, 4G and 5G), terrestrial broadcast, and automotive radar applications, among other uses. RF CMOS technology is crucial to modern wireless communications, including wireless networks and mobile communication devices.
