Abstract
Hybrid RF amplifiers of improved performance are obtained by arranging film resistors, metallization and other components on a circuit board so that symmetrical parts of the electrical circuit are arranged in a mirror symmetrical fashion about a line extending along the circuit board and by aligning symmetrical resistors either parallel or orthogonal to this line and by utilizing common ground metal regions to terminate resistors that are aligned and orthogonal to the mirror line and spaced apart but joined to a common ground at a single location.
