Abstract :
A microwave attenuator has been developed whose attenuation can be controlled by illuminating the silicon substrate. The phase shift which appeared together with the attenuation can be compensated by a ferrite phase shifter under dc magnetic field to the line. The attenuation characteristics without phase shift are shown by experiments in X band and confirmed theoretically by the spectral domain approach.
