Patent ID: 6906600

Claim:
A branching filter comprising: a circuit board; and at least two surface acoustic wave devices for transmission and reception, each of the at least two surface acoustic wave devices comprising: a package having terminals on at least two sides thereof, one of the at least two sides of the package having at least three terminals; and a surface acoustic wave filter mounted in the package; wherein one of the terminals is used for inputting a signal to the surface acoustic wave filter and another of the terminals is used for outputting a signal from the surface acoustic wave filter; and at least one of the terminal for inputting a signal and the terminal for outputting a signal is disposed at the end of one side of the package; wherein the at least two surface acoustic wave devices are disposed on the circuit board such that signal terminals shared by the at least two surface acoustic wave devices are adjacent to each other on antenna sides of the at least two surface acoustic wave devices.
