PHASE SHIFTER AND POLARIZATION SWITCH Abstract of the Disclosure An octave band phase shifter/polarization switch is disclosed which is comprised of a plurality of serially coupled phase bits arranged to provide, in combination, a four bit phase shifter and a polarization switch capable of providing any selected one of six separate polarization senses. The device is fabricated in a stripline package and each of the phase bits is comprised of a hybrid coupler whose output ports are terminated in switchable reactances. Either packaged microwave P-I-N or N-I-P diodes are utilized as the switchable reactances, and bias voltage for the diodes is provided by means of an octave band choke, comprising a dielectrically loaded coil disposed within a center dielectric layer of the stripline package.
