A new class of broadband phase correlators

Summary form only given, as follows. Phase correlators are one of the most basic networks that can be constructed from microwave components like power dividers or hybrid couplers. This work shows the requirements that these devices should fulfill in order to ensure that the correlator circuit works over a large bandwidth. We introduce a new phase correlator structure consisting of one three-stage power divider and three double-stage hybrid couplers. We show that the bandwidth of our structure is larger than commonly used structures.
