Notes/Equations
- The frequency-domain analytical model ignores conductor losses, dielectric losses, and metal thickness.
- A positive (negative) D1 implies that the input line is below (above) the center of the stub-pair.
A positive (negative) D2 implies that the output line is above (below) the center of the stub-pair.
- For time-domain analysis, an impulse response obtained from the frequency-domain analytical model is used.
- The "Temp" parameter is only used in noise calculations.
- For noise to be generated, the transmission line must be lossy (loss generates thermal noise).
- To turn off noise contribution, set Temp to −273.15°C.
