A Digitally Compensated Phase Shifter

A new digitally compensated phase shifter that receives frequency and phase shift information at its inputs and generates the required phase for that frequency by accessing a precisely calibrated look-up table
A Digitally Compensated Phase Shifter COMSAT RSI, Anghel Laboratories Rockaway, NJ Developing a phase shifter that produces a constant or flat phase response with respect to frequency is difficult. Networks that exhibit this type of behavior are narrowband and must be optimized for each specific frequency and desired phase...
