None

CheckPassivity

Check passivity flag: if set to yes, a passivity check is performed and a warning is output if the device is not passive; if set to no, a passivity check is not performed.

None

yes

Delay

##### Notes/Equations
1. Ideal isolation exists for S23 , S24 , S32 , S34 , S42 , and S43 , that is,
S23 = S32 = S24 = S42 = S34 = S43 = 0.
2. Ideal match exists for S11 , S22 , S33 , and S44 , that is,
S11 = S22 = S33 = S44 = 0.
3. S12 = S21 , S13 = S31 and S14 = S41.
4. PwrSplit3 can also be used as a power combiner.
5. Use the functions polar( ), dBpolar( ) to represent the S-parameters in terms of magnitude, phase or dB, phase.
