GAIN - Ideal Gain Block

Model for an ideal gain block. Gain increases to the user defined gain (G) at the use defined lower frequency (FL) at a slope determined by the positive gain slope (SL). The gain stays constant until the user defined upper frequency (FH) at which point, gain will decrease at a rate defined by the negative gain slope (SH). The upper or lower gain slopes can be omitted by setting FL/FH or SL/SH to 0.

CIRC - Ideal Circulator

Model for an ideal universal 3 port circulator. This model is frequency independent.

ISOL - Ideal Isolator

Model for an ideal universal 2 port isolator. This model is frequency independent.

CPLR - Ideal Coupler

Model for an ideal coupler. Coupling is determined by the coupling coefficient (c). Coupling in decibels is calculated as 20*log(c). This model is frequency independent.

GYR - Gyrator

Model for an ideal gyrator. This model is frequency independent.
