Abstract (en)
[origin: US2009206981A1] The invention relates to an RF resistor, and in particular an RF terminating resistor, having a planar layer structure which has, on a substrate (16), a resistive layer (10) for converting RF energy into heat, an input conductor track (12) for the infeed of RF energy, and an earthing conductor track (14) for making an electrical connection to an earth contact, the input conductor track (12) being electrically connected to a first end (18) of the resistive layer (10), the earthing conductor track (14) being electrically connected to a second end (20) of the resistive layer which is opposite from the first end (18), and the resistive layer (10) being bounded, between the first end (18) and the second end (20), by lateral faces (26) in a direction perpendicular to a direction of propagation (22) of the RF energy in the resistive layer (10) and perpendicular to a normal (24) to the planar layer structure, the resistive layer (10) having at least one incision, which at least partly constricts the cross-section of the resistive layer (10), to match the characteristic impedance to a predetermined value. The incision (28) is formed to be spaced away from the lateral faces (26) of the resistive layer (10) in this case.
