powerDividerCorporate

Create corporate power divider

Since R2022a

Description

Use the powerDividerCorporate object to create a corporate power divider to divide power equally or unequally from a single port to multiple ports.

Creation

Syntax

divider = powerDividerCorporate

divider = powerDividerCorporate(Name=Value)

Description

divider = powerDividerCorporate creates a corporate power divider with default properties for an operating frequency of 1.6 GHz.

divider = powerDividerCorporate(Name=Value) sets Properties using one or more name-value arguments. For example, powerDividerCorporate(PortLineLength=0.0300) creates a corporate power divider with an input and output line length of 0.0300 meters. Properties not specified retain their default values.

Properties

NumOutputPorts — Number of output ports

4 (default) | 2 | 8 | 16 | 32 | positive scalar

Number of output ports, specified as a positive scalar.

Example: divider = powerDividerCorporate(NumOutputPorts=8)

Data Types: double

SplitterElement — Basic divider element

"wilkinsonSplitter (default) | "wilkinsonSplitterUnequal" | "wilkinsonSplitterWideband"

Basic divider element, specified as wilkinsonSplitter, wilkinsonSplitterUnequal, or wilkinsonSplitterWideband object.

Example: divider = powerDividerCorporate(SplitterElement="wilkinsonSplitterWideband")

Data Types: char | string

Corner — Shape of corner at each bend

'Mitered' (default) | 'Curved'

Shape of corner at each bend specified as 'Mitered' or 'Curved'. If you set Corner to 'Mitered', specify the miter diagonal by setting the MiterDiagonal property. If you set Corner to 'Curved', specify the radius of the curve by setting the CurveRadius property.

Example: divider = powerDividerCorporate(SplitterElement='Curved')

Data Types: char | string

MiterDiagonal — Length of miter diagonal

0.0025 (default) | positive scalar

Length of the miter diagonal in meters, specified as a positive scalar. This property applies only when you set the Corner property to 'Mitered'.

Example: divider = powerDividerCorporate(MiterDiagonal=0.0046)

CurveRadius — Radius of curve

0.0025 (default) | positive scalar

Radius of the curve at the bends in meters, specified as a positive scalar. This property applies only when you set the Corner property to 'Curved'.

Example: divider = powerDividerCorporate(CurveRadius=0.0046)

Data Types: double

PortLineLength — Length of input and output line

0.0080 (default) | positive scalar

Length of the input and the output line in meters, specified as a positive scalar.

Example: divider =powerDividerCorporate(PortLineLength=0.0070)

Data Types: double

PortLineWidth — Width of input and output line

0.0049 (default) | positive scalar

Width of the input and the output line in meters, specified as a positive scalar.

Example: divider =powerDividerCorporate(PortLineWidth=0.0034)

Data Types: double

GroundPlaneWidth — Width of ground plane

0.0960 (default) | positive scalar

Width of the ground plane in meters, specified as a positive scalar.

Example: divider =powerDividerCorporate(GroundPlaneWidth=0.046)

Example: double

IsShielded — Flag to add metal shielding

false or 0 (default) | true or 1

Flag to add a metal shielding to the PCB component, specified as a logical 0 or logical 1. The default value is logical 0.

Example: IsShielded = true or 1 add a metal shield.

Note

To enable FEM solver required for the metal shield property, download the Integro-Differential Modeling Framework for MATLAB. To download this add-on:

1. In the Home tab Environment section, click on Add-Ons. This opens the add-on explorer. You need an active internet connection to download the add-on.

2. Search for Integro-Differential Modeling Framework for MATLAB and click Install.

3. To verify if the download is successful, run

   matlab.addons.installedAddons

   in your MATLAB^® session command line.

4. On Windows, to run the IDMF add-on, you must install the Windows Subsystem for Linux (WSL). To install WSL, see Install Linux on Windows with WSL.

   The Windows Defender Firewall can block the PostgreSQL server when using the IDMF add-on. To resolve this issue, you can allow the server to communicate on desired networks if the firewall prompts. Alternatively, you can manually add the executable file of the PostgreSQL server located in <matlabroot>\sys\postgresql\win64\PostgreSQL\bin\postgres.exe. For more information, see https://support.microsoft.com/en-us/windows/risks-of-allowing-apps-through-windows-defender-firewall-654559af-3f54-3dcf-349f-71ccd90bcc5c.

Data Types: logical

Shielding — Metal shielding

shape.Box object

This property is read-only.

Metal shield for the PCB component, specified as a shape.Box object. The length and width of the box must be equal to the length and width of the ground plane. The center of the box is at [0 0 Shielding.Height].

Dependencies

To enable the Shielding property, set the IsShielded property to true or 1.

Connector — Type of RF connector

RFConnector object

Type of RF connector assembled at the feed locations of the PCB component, specified as a RFConnector object.

Example: Create connector from RFConnector object like this: coaxial = RFConnector adds a coaxial connector.

Dependencies

To enable the Connector property, set the IsShielded property to true or 1.
