Arguments
Input arguments
# inObj — RF circuit
+
the circuit object
Details
RF circuit defined as an object circuit. One of the elements of the object circuit maybe an object txlineElectricalLength.
# EL1 is the first element
+
the txlineElectricalLength object | scalar
Details
The first element of the chain inObj, set as an object txlineElectricalLength or a scalar. The scalar value indicates the index of the element in the chain. This element must be connected in series with the second element specified in Kuroda’s transformation.
# EL2 is the second element
+
the txlineElectricalLength object | scalar
Details
The second element of the chain inObj, set as an object txlineElectricalLength or a scalar. The scalar value indicates the index of the element in the chain. This element must be connected in series with the first element specified in Kuroda’s transformation.
# EL3 — the third element
+
the nport object | scalar
Details
The third element of the chain inObj, set as an object nport or a scalar. An object nport specifies the ideal transformer, and the scalar value indicates the index of the element in the circuit.
The ideal transformer is realized using a two-port element nport with S-parameter data corresponding to an ideal transformer 1:N or N:1. The transformer must be passive, lossless and frequency independent. The S-parameter data must meet the following conditions S12 = S21 and S12 = N × (1 + S11), where N — the number of turns of the transformer.
This element must be connected sequentially to the first two elements specified in Kuroda’s transformation.
Algorithms
Kuroda’s Transformation
Details
The figure shows how to transform Kuroda or Kuroda identity ( ) are applied to a parallel capacitor, a parallel inductor, a series capacitor, or a series inductor [1].
