ABSTRACT:
In a composite multiplexer circuit designed to multiplex plural frequency bands by interconnecting plural multiplexer circuits in parallel, a multiplexer circuit for extracting a frequency band of a GPS reception system includes a matching network including an inductor and a capacitor, and a surface acoustic wave filter connected in series with the matching network. The multiplexer circuit for the GPS reception system can be so set as to have infinite impedances at the other frequency bands than the frequency band thereof. This prevents signals in the other frequency bands from leaking into the multiplexer circuit for the GPS reception system.
