1. A system for transmitting signals in a mobile network, the system comprising:

  • a transceiver configured to(a) transmit (i) time-division (TD) output signals in a TD transmission/reception band, and (ii) frequency-division (FD) output signals in a FD transmission band, and(b) receive (i) TD input signals in the TD transmission/reception band, and (ii) FD input signals in a FD reception band;

    a single power amplifier configured to amplify both the TD output signals and the FD output signals received from the transceiver, wherein the power amplifier is operable with a bandwidth that covers both the TD transmission/reception band and the FD transmission band; and

    an output terminal having a duplexer, wherein the output terminal is configured to respectively generate transmission signals based on (i) the TD output signals amplified by the power amplifier, and (ii) the FD output signals as amplified by the power amplifier, and wherein the duplexer is configured to receive the amplified FD output signals and output corresponding FD transmission signals to an antenna, and wherein the duplexer is further configured to not receive the amplified TD output signals;

    a switch configured to route the amplified FD output signals to the duplexer and to route the amplified TD output signals to bypass the duplexer,wherein the FD transmission band and the FD reception band are different from each other and from the TD transmission/reception band, andwherein the TD transmission/reception band is adjacent to the FD transmission band.
