Publication number: 20220255567Abstract: The disclosed front end architectures are configured to conglomerate duplexer transmission (TX) contours into a specific or targeted region. This enables the power amplifier (PA) to match a larger number of frequency bands without the help of additional matching networks. The disclosed architectures are advantageous because they reduce the number of components (e.g., surface mount technology components (SMTs)) required for radio-frequency (RF) modules, such as front end modules, power amplifier modules, and the like. The disclosed architectures are also advantageous because they improve performance of the modules across a wider range of frequency bands.Type: ApplicationFiled: December 30, 2021Publication date: August 11, 2022Inventors: Jiunn-Sheng Guo, Tianming Chen, Russ Alan Reisner
