Design Of A BAW Quadplexer Module Using NI AWR Software

This application note describes the design of a carrier aggregation (CA) bulk acoustic wave (BAW) quadplexer module. The module is intended for the LTE-3 and LTE-7 bands, with high in-band and cross-band isolation. Qorvo TQQ1003 and TQQ1007 BAW duplexers  were used for the duplexer and the circuit was designed with the NI AWR Design Environment platform, specifically Microwave Office circuit design software. The design is described in steps: filter, t-junction, diplexer, and quadplexer. Download the application note for more information.
