1. At least one machine readable storage medium having instructions embodied thereon for protecting a power amplifier in a repeater, the instructions when executed by a controller in the repeater perform the following:
- determining, at the controller in the repeater, whether a load is connected to the repeater;
protecting, by the controller, the power amplifier in the repeater when the load is not connected to the repeater by disabling the power amplifier when a return loss on a repeater port coupled to the controller is less than a defined threshold; and
unprotecting, by the controller, the power amplifier in the repeater when the load is connected to the repeater by enabling the power amplifier.

Abstract
Technology for a repeater is disclosed. The repeater can include a power amplifier and a controller. The controller can determine whether a load is connected to the repeater. The controller can protect the power amplifier when the load is not connected to the repeater by disabling the power amplifier. The controller can unprotect the power amplifier when the load is connected to the repeater by enabling the power amplifier.
