Claim 0:
1. A high-frequency front end module comprising:
a primary antenna terminal and a secondary antenna terminal;
a first multiplexer and a second multiplexer; and
a first switch circuit having a first terminal, a second terminal, a third terminal, and a fourth terminal,
wherein the first multiplexer comprises:
a first transmission filter having a pass band comprising a first transmission band; and
a first reception filter having a pass band comprising a first reception band,

wherein the first multiplexer does not comprise a transmission filter having a pass band comprising a second transmission band included in a second frequency band which is different from a first frequency band,
wherein the second multiplexer comprises:
a second transmission filter having a pass band comprising the second transmission band; and
a second reception filter having a pass band comprising a second reception band,

wherein the second multiplexer does not comprise a transmission filter having a pass band comprising the first transmission band,
wherein a band extending from minimum pass band frequency to a maximum pass band frequency of the filters of the first multiplexer at least partially overlaps a band extending from a minimum pass band frequency to a maximum pass band frequency of the filters of the second multiplexer,
wherein the first terminal is connected to the primary antenna terminal,
wherein the second terminal is connected to the secondary antenna terminal,
wherein the third terminal is connected to an output terminal of the first transmission filter and to an input terminal of the first reception filter, and
wherein the fourth terminal is connected to an output terminal of the second transmission filter and to an input terminal of the second reception filter.
