In a radio communication apparatus comprising a transmitting portion (12) supplied with input baseband signals for selectively transmitting the input baseband signals in response to a selection signal (13), the transmitting portion comprises a selector (22) for selecting one of the input baseband signals as a selected baseband signal in response to the selection signal. A level controller (23) has a controllable gain and controls the selected baseband signal so that the selected baseband signal has a level which is determined by the controllable gain. A gain controller (24) has predetermined gains in correspondence to the input baseband signals and controls the controllable gain in response to the selection signal so that the controllable gain becomes equal to one of the predetermined gains that corresponds to the selected baseband signal. A converter (18-20) converts the selected baseband signal into a radio signal carrying the selected baseband signal. The gain controller may comprise a memory (25) for memorizing the predetermined gains. Responsive to the selection signal, a reading circuit (26) reads from the memory, as a read-out gain, one of the predetermined gains that corresponds to the selected baseband signal. A control circuit (27) controls the controllable gain so that the controllable gain becomes equal to the read-out gain.
