Other Phasing Devices
The following topics are important, but didn't seem to fit neatly anywhere else.
The 3 presentations below are for:
180 degree duHamel coupler
90 degree LC phase network (a 1967 simulation benchmark)
90 degree Gingell Polyphase RC network
and here is a javascript routine for designing Polyphase networks with optimum RC values for an equal ripple error:
Just a two-slide sim result below duplicating the results of Carl Pfeiffer at Microwaves101 for an asymmetric tapered line 180 degree duHamel coupler. Carl's simulation is here .
A goodfirst example for QucsStudio: A phase difference network with 32 LC elements.
