CHIP HAVING FOUR FILTERS OPERATING WITH SURFACE ACOUSTIC WAVES

摘要

The invention relates to a chip (CH) which has four filters (Fl, F2, F3, F4 ) operating with surface acoustic waves, and input ports and output (EP1, EP2, API, AP2). Each filter (Fl, F2, F3, F4 ) covers a different frequency band. Each of the input and output ports (EP1, EP2, API, AP2) is connected to one or two filters (Fl, F2, F3, F4 ).
