Methods, systems, and circuities for selectively connecting an RF signal to front end circuitry and selectively attenuating the RF signal are disclosed. In one example, an interface circuitry includes switching circuitry and attenuator circuitry. The switching circuitry is connected in series between an output of an amplifier and a front end circuitry configured to transmit a radio frequency (RF) signal output by the amplifier. The switching circuitry connects the output of the amplifier to a selected one or more front end circuitry inputs to create one or more signal paths. The attenuator circuitry is connected between the output of the amplifier and ground to create an attenuation path in a shunt configuration relative to the one or more signal paths. The attenuator circuitry is configured to attenuate the RF signal.
