WIPO Patent Application WO/2014/024761
Kind Code:
A1
Abstract:
A bandstop filter (11) is provided on a cellular signal line. A SAW filter (28) and a bandstop filter (21) are provided on a GPS signal line. The bandstop filter (21) is disposed between an antenna port (P1) and the SAW filter (28). The bandstop filter (11) reflects GPS signals (giving the appearance of openness to the antenna port at the GPS signal frequency), and allows cellular signals to pass. Of the cellular signals, the bandstop filter (21) reflects high-band signals that are close to the frequency band of the GPS signals (giving the appearance of openness to the antenna port at the high-band signal frequency), and allows GPS signals to pass.
