<p>Four generally quadrant-like indentations (4a, 4b, 4c, 4d) are formed at the corners of a substrate (2). A conductive member is applied to the inner surfaces of the indentations to form input and output terminals, namely a power voltage terminal (P), a voltage control terminal (VC), a modulation terminal (M), and an output terminal (P). By placing these terminals at the corners of the substrate, sufficient distances are provided between the input terminals and the output terminals so as to prevent interference between these terminals. <IMAGE></p> |
