1. A surface mount component comprising:
a monolithic substrate;
an input terminal, an output terminal, and a DC bias terminal, each formed over the monolithic substrate;
a conductive trace formed over a surface of the monolithic substrate included in a signal path between the input terminal and the output terminal; and
a thin-film resistor connected in a DC bias path between the DC bias terminal and the signal path;
wherein the DC bias path, at one or more locations along the DC bias path between the DC bias terminal and the signal path, has a cross-sectional area in a plane that is perpendicular to the surface of the monolithic substrate, and wherein the cross-sectional area of the DC bias path is less than about 1,000 square microns, and
wherein the thin-film resistor is directly electrically connected with each of the DC bias terminal and the output terminal.
