Hybrid Coupler Pin Configuration
The X3C21P1-03S has an orientation marker to denote Pin 1. Once port one has been identified the other ports are
known automatically. Please see the chart below for clarification:

*Notes: “A” is the amplitude of the applied signals. When two quadrature signals with equal amplitudes are
applied to the coupler as described in the table, they will combine at the output port. If the amplitudes are
not equal, some of the applied energy will be directed to the isolated port.
The actual phase, ^∠θ , or amplitude at a given frequency for all ports, can be seen in our de-embedded s-
parameters, that can be downloaded at www.anaren.com.
