GAIN - Ideal Gain Block

NameDescriptionUnitsDefault Value
AGaindecibels0.0 dB
SLPositive gain slopedB/octave6.0 dB/octave
SHNegative gain slopedB/octave6.0 dB/octave
FLLower frequency for SLFrequency0.0 MHz
FHUpper frequency for SHFrequency0.0 MHz
RReference impedanceResistance50 ohms


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

NameDescriptionUnitsDefault Value
cCoupling coefficientunitless0.1


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.
