rfdivider

Create three-port Wilkinson power divider element for circuit object

Since R2023a

Description

Use the new rfdivider object to create a three-port Wilkinson power divider element. You can add this object to your circuit object to create an RF circuit.

Creation

Syntax

rfpd = rfdivider

rfpd = rfdivider(Name=Value)

Description

rfpd = rfdivider creates a three-port Wilkinson power divider element with default property values.

rfpd = rfdivider(Name=Value) sets Properties of the power divider element using one or more name-value arguments. For example, rfpd = rfdivider(Impedance=75) sets the impedance of the Wilkinson power divider element to 75 ohms. Properties not specified retain their default values.

Example: 'Divider_Wilk'

Data Types: char | string

Impedance — Reference impedance of Wilkinson power divider element

50 (default) | positive scalar

Reference impedance of the Wilkinson power divider element, specified as a positive scalar.

Example: 75

Data Types: double

NumPorts — Number of input and output ports

3 (default) | positive scalar

This property is read-only.

Examples

Add Wilkinson Power Divider Element to Circuit Object

Create a default three-port Wilkinson power divider element.

pd = rfdivider(Name='rfdivider1');

Clone the three-port Wilkinson power divider element.

pd2 = clone(pd);
pd2.Name='rfdivider2';

Create an amplifier element of gain 12 dB.

amp = amplifier(Name='amplifier1',Gain=12);

Clone the amplifier element.

amp2 = clone(amp);
amp2.Name = 'amplifier2';

Create a circuit object.

ckt = circuit;

Add the divider named rfdivider1 to the circuit object.

add(ckt,[1 2 3],pd);

Add the amplifier named amplifer1 to the circuit object.

add(ckt,[2 4],amp);

Add the amplifier named amplifer2 to the circuit object.

add(ckt,[3 5],amp2);

Add the divider named rfdivider2 to the circuit object.

add(ckt,[6 4 5],pd2);

Use the setports function to set ports of the circuit object.

setports(ckt,[1 0],[6 0],{'in','out'});

Display the circuit object.
