RF Front End (LNA + PA)


Products in this family are integrated circuits that integrate one or more of the functions commonly found in the portion of a radio frequency (RF) signal chain that is connected to the system's antenna, such as a low-noise amplifier (LNA) and programmable amplifier (PA). The actual functionality incorporated into any given device varies, with devices targeting relatively narrow applications typically integrating a larger portion of the requisite signal chain than those intended to be more flexible in their application.
