Design of a BAW Quadplexer Module Using NI AWR Software

With the development of the LTE-Advanced and OFDMA techniques, multiple-carrier technology has become important in the mobile communication industry. Designers are meeting the challenge of working with multi-carrier signal-frequency systems by using diplexers and duplexers in RF circuits to separate different carriers.  

This application note describes the design of a carrier aggregation (CA) bulk acoustic wave (BAW) quadplexer module  for the LTE-3 and LTE-7 bands, with high in-band and cross-band isolation.
