Abstract : The performance of a conventional p-i-n diode microwave phase shifter is directly compared, in this report, to that of a fiber-optic microwave phase shifters. The fiber-optic system is based upon the technique of fiber stretching, which produces a continuous true-time delay in contrast to the discrete nature of tne p-i-n diode phase shifter. The proliferation of microwave fiber-optic links has driven the effort to develop fiber-optic equivalents to standard microwave components. Comparisons are made between the two systems bandwidth, maximum phase shift, amplitude stability, phase accuracy, shifting speed, sideband suppression, insertion time delay, insertion loss, size and power consumption.
