1. A dual-mode front end module (FEM), comprising:
- an antenna switch module (ASM);
a first filtering unit which filters signals of a first type that are outputted from the ASM;
a single pole double throw (SPDT) switch;
a second filtering unit which filters signals of a second type that are inputted to or outputted from the SPDT switch; and
at least one antenna port for transmitting and receiving at least one of the signals of the first type and the signals of the second type.

Abstract
A dual-mode front end module (FEM) includes an antenna switch module (ASM), a first filtering unit which filters signals of a first type that are outputted from the ASM, a single pole double throw (SPDT) switch, a second filtering unit which filters signals of a second type that are inputted to or outputted from the SPDT switch, and at least one antenna port for transmitting and receiving at least one of the signals of the first type and the signals of the second type.

8. A mobile terminal, comprising:
-
a dual-mode front end module (FEM);
a first RF unit that processes RF signals of a first type outputted from the dual-mode FEM;
a first baseband processing unit that processes baseband signals outputted from the first RF unit;
a second RF unit that processes RF signals of a second type outputted from the dual-mode FEM; and
a second baseband processing unit that processes baseband signals outputted from the second RF unit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of communicating signals of a first type and signals of a second type with a mobile terminal, comprising:
-
receiving RF signals of a first type and RF signals of a second type by a dual-mode front end module (FEM) of a mobile terminal;
outputting, by the dual-mode FEM, the RF signals of the first type to a first RF unit that processes the RF signals of the first type; and
outputting, by the dual-mode FEM, the RF signals of the second type to a second RF unit that processes the RF signals of the second type. - View Dependent Claims (17, 18, 19, 20)
