Notes/Equations
  1. This model works in transient and circuit envelope simulation.
  2. Up to three frequency break points can be used to define four bands, with different losses and VSWR for each frequency band. Losses are entered as a positive attenuation. In other words, a 0.5 dB loss is entered as L1=0.5, not L1=−0.5.
    Isolation is assumed to be constant across all frequency bands.
    When using this device in a transient simulation, the switch setting must be constant.
    If loss values are specified versus frequency via a dataset and using the component DATASETVARIABLE, then a time delay through the device will be introduced when using transient analysis.
    Transient Analysis Time Delay = (1/(2 × MAX_FREQUENCY)) × POINTS
    where
    POINTS = (FILTER_ORDER/2) − 1 for FILTER_ORDER even
    = (FILTER_ORDER + 1)/2 − 1 for FILTER_ORDER odd
