    摘要: A filter chip lying on an upper surface of a top layer package substrate is connected to an upper surface ground electrode (235). The upper ground electrode (235) and a lower surface ground electrode (237) are connected to each other via through electrodes (261, 262, 263), ground wiring patterns (251, 252), first connecting lines (271 to 276), and second connecting lines (281, 282). The first connecting lines (271 to 276) are connected to the ground wiring patterns (251, 252), whereas the second connecting lines (281, 282) are not connected to the ground wiring patterns (251, 252), respectively. Owing to the provision of the connecting lines connected to the ground wiring patterns (251, 252) and the connecting lines unconnected to the ground wiring patterns (251, 252), the impedance between a multilayer package substrate and ground can be adjusted.

    摘要: A surface-acoustic-wave filter has a pair of series-arm surface-acoustic-wave resonators and a shunt-arm surface-acoustic-wave resonator coupled in a T configuration. An additional bridging surface-acoustic-wave resonator is coupled between the input and output terminals, in parallel with the series arm. The bridging surface-acoustic-wave resonator provides enhanced attenuation of spurious signals at multiples of the passband frequency.
