ACFM-7325 applications information the ACFM-7325 quadplexer has a single antenna con- nection common to the both the cellular and pcs band duplexers. operation a two-element series-l, shunt-c network is used to match the impedance of the ant port to 50 ohms as shown in figure 1. matching components the nominal values for l and c shown here were selected to match the ACFM-7325 to 50 ohms. since every appli- cation is different, these nominal values may need to be adjusted to provide the best impedance match for the users particular circuit board, performance requirements, and interface to related components. the l and c matching components should be located in close proximity to the quadplexer as shown in the recom- mended pcb layout. the maximum tolerance for the matching components should be 5% for the inductor and 0.2 pf for the capacitor. the inductor should be of the high q type (e.g., murata lqw15an5n1d00d). system ant 5.1 nh 1.0 pf ant cell tx pcs rx port 4 port 1 port 3 cell rx port 5 pcs tx port 2
