RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Phase Shifters, Tuners & Delay Lines
Manufacturers & Services

Phase 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.
