Patent ID: 8559893

Claim:
A front end module comprising: an antenna path; and a triplexer that is connected to the antenna path, to a first signal path, to a second signal path, and to a third signal path; a first switch to connect the first signal path to one of at least four first partial paths; a second switch to connect the second signal path to one of at least four second partial paths; a substrate; and at least one chip that is on the substrate, the triplexer comprising part of the substrate and part of at least one chip on the substrate; wherein the first signal path is for transmitting signals in at least two first frequency bands that are for different transmission systems; wherein the second signal path is for transmitting signals in at least two second frequency bands that are for different transmission systems; wherein the third signal path is for transmitting signals in a third frequency band; wherein a passband of the third signal path is between passbands of the first signal path and the second signal path; wherein the triplexer comprises a low-pass filter that is connected to the first signal path and a high-pass filter that is connected to the second signal path; wherein the triplexer comprises a band-pass filter that is connected to the third signal path; wherein the high-pass filter comprises a capacitor and an inductor that are electrically connected, and the low-pass filter comprises a capacitor and an inductor that are electrically connected; and wherein the band-pass filter comprises a surface acoustic wave (SAW) filter or a bulk acoustic resonator (BAW) filter.
