Hello Guys:
can anyone help me to solve this question: how to define a 3-port directional coupler's directivity (4th port ISO is internally terminated).
normally, directivity is defined in such a way： D=S31/S32 (Port 1: input, Port2: output, Port3: Coupling port), with ISO port internally...
Hi guys:

i do not...
Hi guys:
