Disclosed are various embodiments for a pre-matched power resistance system including a pre-matching network for use with a passive electrical device, such as a Lange coupler or a Wilkinson power splitter, where the system provides a predetermined input impedance across a predetermined target bandwidth. The pre-matched power resistance system network further includes an on-chip thin film resistor disposed on a substrate comprising a plurality of coplanar sub-resistors electrically isolated from one another and a manifold portion comprising a plurality of manifold traces in a tiered arrangement terminating in an electrical connection to a respective one of the coplanar sub-resistors.
