Microwave attenuator module

摘要

An attenuator module having a substrate; a attenuator disposed on one surface of the substrate, the attenuator having an input terminal at one end of the attenuator and an output terminal at an opposite end of the attenuator; an electrical conductor disposed on an opposite surface of the substrate; and an electrically conductive via passing from the output terminal through the substrate to the electrical conductor disposed on the opposite surface of the substrate.

1. An electrical circuit, comprising:
a monolithic microwave integrated circuit having an amplifier; a first substrate having a microwave transmission line, the microwave transmission line having: a signal conductor disposed on an upper surface of the first substrate and connected to the amplifier through a conductor disposed over the upper surface of the first substrate; and a ground plane conductor; an attenuator module, comprising:
a second substrate;an attenuator disposed on an upper surface of the second substrate, the attenuator having an input terminal on the upper surface at one end of the attenuator connected to the conductor disposed over the upper surface of the substrate and an output terminal on the upper surface at an opposite end of the attenuator, the attenuator having an attenuation element disposed between the input terminal and the output terminal;an electrical conductor disposed on a bottom surface of the second substrate;an electrically conductive via passing from the output terminal through the second substrate to the electrical conductor disposed on the bottom opposite surface of the second substrate; and wherein the electrical conductor disposed on the bottom surface of the second substrate is disposed in electrical contact with the signal conductor of the first substrate; and wherein the input terminal is electrically isolated from the signal conductor of the first substrate.
