More specifically, an apparatus including a chain of directional couplers is used to distribute radio frequency power. The apparatus may also include a set of gain controllers. Each particular gain controller of the set of gain controllers is associated with a particular directional coupler of the chain of directional couplers, and each particular gain controller is configured to adjust a radio frequency power for the associated particular directional coupler.
