ABSTRACT:
The present invention is an electronic device including a submount for mounting a component thereon. The submount includes a first high speed transmission line electrically coupled to a contact for providing electrical contact to the component. At least two load resistors are also formed on the submount and electrically coupled to the contact. A second high speed transmission line is coupled between the two resistors to a ground electrode. The impedance and inductance of the second transmission line is desirably such as to provide a loss v. frequency characteristic that is essentially opposite to that of the first transmission line so as to produce a combined characteristic which is essentially flat.
