摘要： A surface-acoustic-wave filter couples a two-port surface-acoustic-wave resonator filter circuit coupled in parallel or in series with a two-port impedance circuit. The two-port impedance circuit has an impedance that creates a pole of attenuation, by making the open-circuit impedance of the surface-acoustic-wave filter equal to the short-circuit impedance. High attenuation over a wide range of stopband frequencies is obtained in this way, combined with steep roll-off between the passband and stopband.

摘要： A surface acoustic wave filter includes an antenna terminal, an antenna, a transmitting filter, a branching line and a receiving filter. The antenna is coupled to the antenna terminal. The transmitting filter is coupled to the antenna terminal. The transmitting filter receives an electrical power. The branching line is coupled to the antenna terminal. The branching line has a first length that is longer than λ/4 length so that the electrical power received by the transmitting filter when the antenna terminal is opened is smaller than when the antenna terminal is terminated, wherein λ is a wave length of a center frequency of transmitted and received bands of the surface acoustic wave filter. The receiving filter is coupled to the branching line.

摘要： In a differential surface acoustic wave resonator, when an unbalanced electric signal is inputted between an input terminal 301 and an output terminal connected to a ground potential, this electric signal is inputted to two-terminal-pair surface acoustic wave resonators 351 and 352. The electric signal inputted to the two-terminal-pair surface acoustic wave resonator 351 is converted into a surface acoustic wave, and thereafter it is again converted into an electric signal to be outputted to a two-terminal-pair surface acoustic wave resonator 353. The electric signal inputted to the two-terminal-pair surface acoustic wave resonator 353 is converted into a surface acoustic wave, and thereafter it is again converted into an electric signal to be outputted from an output terminal 302 of the differential surface acoustic wave filter as a balanced signal. On the other hand, the electric signal inputted to the two-terminal-pair surface acoustic wave resonator 352 is converted into a surface acoustic wave, and thereafter it is again converted into an electric signal to be outputted to a two-terminal-pair surface acoustic wave resonator 354. The electric signal inputted to the two-terminal-pair surface acoustic wave resonator 354 is converted into a surface acoustic wave, and thereafter it is again converted into an electric signal to be outputted from an output terminal 303 of the differential surface acoustic wave filter as a balanced signal. Here, in the respective two-terminal-pair surface acoustic wave resonators 351 to 354, the phase of the electric signal to be inputted is substantially 180° different from that of the electric signal to be outputted. The balanced signals having the same phase and the same amplitude are outputted from the two output terminals of the differential surface acoustic wave filter.
