Notes/Equations
- Although hybrid couplers are typically designed to give an equal power split between the coupled and the direct ports, the choice of coupling coefficient has been provided here for greater flexibility where a coupling of other than 3 dB is required.
- The loss term is applied to both the coupling and the direct transmission coefficients.
- Pin designations (directional coupler notation/sum-difference notation):
(IN) = input port/input port#1
(IS0) = isolated output/input port #2
( Σ) = coupled output/summation output
(Δ) = direct output/difference output
- When used in time domain simulation, set PhaseBal=0; for any PhaseBal value other than n × 180, time domain simulation will not produce proper results because the frequency domain specification corresponds to a non-causal impulse response in time domain.
- This component has no default artwork associated with it.
