ABSTRACT:
A microstrip integrated circuit reflection amplifier utilizing packaged diodes and permitting some gain and bandwidth adjustment. A 3 db quadrature coupler has two of its ports connected to substantially identical reflection amplifiers. The reflection diodes are adjustably mounted in brackets perpendicular to the dielectric substrate of the microstrip network and may be moved in and out along the microstrip circuit to provide for some gain correction and bandwidth adjustment.
