Abstract: A mobile terminal according to the present invention includes a transceiver to operate in a first communication system and a second communication system, a first antenna to transmit or receive a first signal of the first communication system, a second antenna to transmit or receive a second signal of the second communication system, and a signal attenuator module to perform signal attenuation for the first signal on a path between the second antenna and a low noise amplifier (LNA) of the second communication system, whereby system damage in a non-synchronized state between the first and second communication systems can be avoided.
