Abstract : The patent relates to a method of inserting into a phase shifter the necessary amount of insertion phase shift to correct for departure of phase shift from an acceptable value for that phase shifter resulting from normal inadequate production tolerances. The method involves using in the logic-driver circuit for the phase shifter a counter whose digital output determines the magnitude of the phase shift command applied to the phase shifter. The input to the counter is preset in accordance with the amount of phase shift correction determined from the phase shift measuring test to be necessary to correct for the undesired phase deviation in the manufacturing process.
