Abstract
An amplifier module with multiple operating modes is described. In an exemplary design, the amplifier module includes an amplifier (e.g., a power amplifier), a switch, and an output circuit. The amplifier receives and amplifies an input signal and provides an amplified signal in a first mode. The switch is coupled to the output of the amplifier and bypasses the amplifier and provides a bypass signal in a second mode. The output circuit is coupled to the amplifier and the switch. The output circuit performs output impedance matching for the amplifier in the first mode. The output circuit also (i) receives the amplified signal and provides an output signal in the first mode and (ii) receives the bypass signal and provides the output signal in the second mode. The amplifier is enabled in the first mode and disabled in the second mode.
