Coexistence is probably one of the biggest concerns for most radio front- end designers. More devices are supporting multiple protocols at the same time, and that can become a nightmare for an RF designer trying to maintain a reliable signal. Qorvo offers solutions to address these challenges." C h a p t e r 2 | O v e r c o m i n g T e c h n i c a l B a r r i e r s i n N e x t - G e n R F By using acoustic waves in piezoelectric materials to achieve steep rejection curves, BAW filters help teams handle higher power levels while significantly reducing board layout area compared to traditional ceramic alternatives. These steep rejection characteristics isolate signals that are physically adjacent in the spectrum, helping systems effectively manage coexistence. Beyond filtering, systems need to discern weak signals from the inherent noise of the receiver architecture. High-performance, low-noise amplifiers (LNAs) empower the system to amplify these signals without distortion for more reliable communication within high- noise environments. In particular, high-linearity LNAs enable the system to amplify weak signals without distortion, even in the presence of interferers. Integrating high-isolation switches further supports signal integrity by effectively managing the transition between transmit and receive paths. Because high isolation prevents the transmitter signal from leaking into the sensitive receive path, it protects the system from internal interference that would otherwise lead to desensitization.
