    Description

    Use the new mutualInductor object to create a mutual inductor element. You can add a mutual inductor element to your rfbudget object, circuit object, or in the RF Budget Analyzer app and then export to the mutual inductor RF Blockset™.

    Creation

    Syntax

    mi = mutualInductor
    mi = mutualInductor(Name=Value)

    Description

    mi = mutualInductor creates a mutual inductor element with default property values.

    mi = mutualInductor(Name=Value) sets Properties of the mutual inductor element using one or more name-value arguments. For example, mi = mutualInductor(CouplingCoefficient=0.65) sets the coupling coefficient between the two coils to 0.65. Properties not specified retain their default values.

    Create a mutual inductor element with the primary inductance of 33 nH, secondary inductance of 26 nH, and the coupling coefficient of 0.55.

    mi = mutualInductor(Inductance1=33e-9,Inductance2=26e-9,CouplingCoefficient=0.55);

    Create an amplifier object with a gain set of 10 dB and the noise figure of 2 dB.

    a = amplifier(Gain=10,NF=2);

    Create a default attenuator object.

    att = attenuator;

    Create a circuit object and name it.

    ckt = circuit('adding_mutual_inductor_to_circuit');

    Add the amplifier, mutual inductor, and the attenuator elements to the circuit object.

    add(ckt,[1 2],a);
add(ckt,[2 3],mi);
add(ckt,[3 4],att);
setports(ckt,[1 0],[4 0]);
