A superconducting linear phase modulator using a single film device made of Tl‐Ca‐Ba‐Cu‐O for operation at 77 K is presented. The modulator has been analyzed from 300 MHz to about 6 GHz with good linearity for peak phase deviations up to 100 rad. Modulation has been observed for carriers up to 35 GHz.
