摘要：
With 5G development and employment, Carrier Aggregation (CA) is a must-have in radio frequency (RF) front end modules (FEM), as this enables higher data transfer rate with wider operation bandwidth. To support CA, multiple filters need to be ganged together at input. Therefore, they will be loading to each other and degrading insertion loss (IL) in each filter. This paper describes some general design techniques to reduce the loading. We show a triplexer design case study, where the lowest frequency filter topology and matching impacts on the whole triplexer performance are discussed.
