ABSTRACT:
A fixed attenuator for microwave band comprising of a dielectric substrate, with a resistance film and a conductor film attached on said substrate so as to form an attenuation circuit. The substrate further comprises of at least one hole provided through the dielectric substrate. The attenuator is mounted on a metallic board or a printed circuit board by a screw inserted in said hole. Thus, the cooling effect of the resistance film has been improved while keeping the low manufacturing cost and stable structure, by fixing the dielectric substrate on a metallic board by screws inserted in the mentioned holes.
