Apparatuses and methods for directional coupling are disclosed. In one embodiment, an apparatus includes a directional coupler, a termination impedance, a switch, and a control block. The directional coupler includes a power input terminal, a power output terminal, a couple terminal and a terminate terminal. The power input terminal can receive a radio frequency signal from a power amplifier, and the power output terminal can be electrically connected to a load. The switch has an ON state and an OFF state, and includes an input electrically connected to the terminate terminal and an output electrically connected to the termination impedance. The switch is configured to provide a relatively low impedance path between the input and the output when in the ON state and to provide a relatively high impedance path between the input and the output when in the OFF state. The control block can set the state of the switch.
An apparatus comprising:
A method for selecting the termination impedance of a directional coupler in a power amplifier module, the method comprising:
A computer-readable storage medium comprising instructions that when executed by a processor perform a method for selecting the termination impedance of a directional coupler in a power amplifier module, the method comprising:
An apparatus comprising:
