5G RF Front-End Module Design: PAs, LNAs, and Filters
Most 5G radio channels, from sub-6 GHz small cells to phased-array mmWave modules, rely on four core functions in their transmit and receive paths: power amplification (PA), low-noise amplification (LNA), RF switching, and bandpass filtering. How those functions are packaged varies widely. Some designs use discrete components, while others integrate them into front-end modules (FEMs), […]
