Notes/Equations
- The output frequency spectrum is equal to the input spectrum shifted by the specified phase.
- θ (f) = Phase (for freq < FreqStart)
θ (f) = Phase + PhaseSlope × LOG2 (freq / FreqStart) (for freq ≥ FreqStart)
if FreqStart = 0, then phase slope is 0 regardless of the PhaseSlope setting
where freq = simulation frequency 
if RTConj = NO, S12 = S21
if RTConj = YES, S12 = S21*- The S-parameter implementation for the phase shifter is shown here:
- This component is intended for use with RF simulators, such as S-parameter, AC, HB, and in Circuit Envelope. It is not recommended for use in transient or baseband envelope simulations.
