Technology for a repeater is disclosed. The repeater can include one or more amplification and filtering signal paths. The repeater can include a controller. The controller can detect an oscillation in the repeater. The controller can reduce a gain in the repeater by a first amount to cease the oscillation in the repeater. The controller can reduce the gain in the repeater further by a second amount to create an oscillation margin. The controller can modify the gain in the repeater further by a third amount to create an offset to the oscillation margin.
