ABSTRACT:
An attenuator element, for high frequency electrical signals, at a characteristic impedance such as 50 ohms. One or more distributed resistance regions are interposed between an input and an output and are coupled to a ground pad. The impedance of the distributed resistance portion or portions is higher than the desired 50 ohms and additional input and output resistances, nondistributed, are interposed between the input pad and the ground pad and between the output pad and the ground pad to bring the effective impedance at the input and output to the desired characteristic impedance level. Utilizing the nondistributed resistances at input and output increases the power capability of the attenuator element and also results in a larger size for the distributed resistance region or regions, providing less critical tolerances for producing the distributed resistance regions.
