An RF tuner is a circuit module or standalone equipment that detects radio-frequency (RF) signals usually of low amplitude and amplifies and converts them to a form suitable for further processing.

What is 4G?
4th generation technology that will provide voice, data and streamed multimedia to users on an “anytime, anywhere” basis, and at higher data rates than current generations allow. Objectives for 4G include wired and wireless technologies capable of providing 100Mbps and 1Gbps speeds both indoors and outdoors. 4G will succeed current 3G WCDMA/HSDPA/HSUPA technology.
