Work is that signal is exported by the second output port again after the first output port input of quadrature bridge 130, completes straight-through transmission.
It should be noted that making signal phase when the first band logical combiner 110 and the second band logical 120 reflected signal of combiner
Upset 180 degree is not unique, and according to the difference of actual design, 180 degree is not necessarily herein, such as phase during open circuit design
0 degree of upset, short-circuit phase bit flipping is only 180 degree, but designs in any case, and the phase of two band logical combiner upsets will be kept
Identical, upset difference when making reflection is 0 degree, i.e., do not change the phase difference value of original signal.
