Claim:
1. An RF attenuator device comprising: an RF input port and an RF output port; a substrate having a first major surface and a second major surface, the substrate being thermally conductive and electrically insulative, the substrate including a ground portion disposed on at least the second major surface; a coupling structure disposed on the substrate, the RF input port being configured to direct an RF input signal to the coupling structure, the coupling structure being configured to couple a predetermined coupled portion of the RF input signal within a predetermined frequency band to provide an RF output signal to the RF output port; a resistor disposed on at least a majority of the first major surface and coupled between a tuning circuit and the ground portion, the resistor being configured to substantially direct an uncoupled portion of the RF input signal to the ground portion; and a connective circuit coupled between the coupling structure and the resistor, the connective circuit being configured to substantially direct the attenuation power to the resistor.
