shifters are used in applications where there is a need to equalize the delay (phase) of signals from one or more
paths to provide functions like interference cancellation, determine angle of arrival (phased arrays), compare signals,
etc. Phase shifters can be as simple as a short length of cable or as complex as electronically adjustable, computer-controlled
systems. Whatever your need, these companies can fulfill your needs for phase shifters, tuners, and delay lines.
