ABSTRACT:
According to the invention, a microstrip microwave frequency attenuator comprises a distributed series resistance medium and distributed shunt resistance medium, wherein the shunt resistance medium is disposed parallel to the direction established for electric fields in the microstrip between the signal path and ground through the energy supporting medium. In the preferred embodiment, the series resistance path has a resistance value per unit length equal to about one-third of the resistance value per unit length compared to the shunt resistance path between the series resistance path and the ground plane.
