Design and Analysis of a RF Front-End Receiver System Based on Multi-Layer Organic Filtering for Sub-6 GHz Mobile Communication Applications

This paper describes a front-end architecture for an all-band direct sampling receiver. To evaluate the characteristics of this front-end, we conducted a S-parameter analysis to evaluate the performance of transmission and isolation of individual transmission channels. Our results prove high mutual isolation of the channels filtered by Multi-Layer Organic (MLO) filters. The effect of individual filter techniques is compared. Furthermore, the frequency planning is described. Finally, the usability of this front-end within a mobile network is discussed.
