Abstract : The patent describes bypass and attenuation paths which are provided through respectively switched diodes. The diodes in the bypass path are turned on in response to direct current of one polarity, and off in response to the opposite polarity, and conversely for the diodes in the attenuate path. Filters are provided to exclude direct current from the bypass and attenuation paths, and to exclude RF from the source of direct current. Equalizers and compensators associated with each path allow phase-shift and attenuation to be accurately adjusted.
