RF Front End modules, typically comprising a Low Noise Amplifier (LNA) and Power Amplifier (PA), are critical in enhancing the signal strength and quality in RF communication systems. These modules are used in applications ranging from mobile devices to radar systems, where both signal reception and transmission need optimization.

Major manufacturers like Skyworks Solutions, Qorvo, and Broadcom design and produce advanced RF front end modules that offer high performance, efficiency, and integration.

Key considerations for selecting an RF front end include gain, noise figure, power output, and linearity. High-quality front-end modules ensure superior performance and reliability in demanding RF applications.
