pcbcascade

Create new component using cascade operation

Since R2021b

Syntax

combinedcomponent = pcbcascade(component1,component2)

combinedcomponent = pcbcascade(component1,component2,m,n)

pcbcascade(component1,component2,'Interactive',true)

combinedcomponent = pcbcascade(___,'RectangularBoard',true)

combinedcomponent = pcbcascade(___,'GroundFloodFill',true)

Description

combinedcomponent = pcbcascade(component1,component2) creates a new component by using a cascade operation along port 2 of the first component and port 1 of the second component.

combinedcomponent = pcbcascade(component1,component2,m,n) creates a new component by using a cascade operation along port m of the first component and port n of the second component.

Note

• pcbcascade only supports: 2-metal layer PCB components, feeds specified at the edge of components, and identical substrate properties in both components.

• If either of the components is an antenna, the new component that the object creates is a pcbStack object.

• To use pcbStack object you require Antenna Toolbox™.

pcbcascade(component1,component2,'Interactive',true) opens a graphical user interface allowing the user to perform the following actions:

• Interactively select and/or re-select which ports to cascade

• Preview the cascade before finalizing the design

• Name and save the design as a PCB Component

combinedcomponent = pcbcascade(___,'RectangularBoard',true) allows the user to create a rectangular BoardShape when set to logical true. By default RectangularBoard is true.

combinedcomponent = pcbcascade(___,'GroundFloodFill',true) allows the user to create a rectangular GroundShape when set to logical true. By default GroundFloodFill is true.

Examples

Create Component From Branchline Coupler and Coupled Microstrip Line

Create a new component by cascading a branchline coupler with a coupled microstrip line.

c = design(couplerBranchline,5.6e9);
mc = design(coupledMicrostripLine,5.6e9);
mc.Spacing = c.ShuntArmLength;
r = pcbcascade(c,mc);

pcbcascade(component1,component2,'Interactive',true)

Input Arguments

component1 — PCB component or antenna

PCB component object | antenna object

PCB component or antenna, specified a PCB component object or antenna object. For a complete list of the PCB components, see PCB Components Catalog.

Example: mline1 = microstripLine; mline2 = design(microstripLine,3e9); component = pcbcascade(mline1,mline2) creates a new component by cascading mline1 and mline2.

Data Types: char | string

component2 — PCB component or antenna

PCB component object | antenna object

PCB component or antenna, specified a PCB component object or antenna object. For a complete list of the PCB components, see PCB Components Catalog.

Example: mline1 = microstripLine; mline2 = design(microstripLine,3e9); component = pcbcascade(mline1,mline2) creates a new component by cascading mline1 and mline2.

Data Types: char | string

m — Port number of first component

1 (default) | positive scalar

Port number of the first component, specified as a positive scalar.

Example: coupler = couplerRatrace;mline = microstripLine;component = pcbcascade(coupler,mline,3,1) creates a new component by cascading Port 3 of the coupler to Port 1 of the microstrip transmission line.

Data Types: double

n — Port number of second component

1 (default) | positive scalar

Port number of second component, specified as a positive scalar.

Example: coupler = couplerRatrace;mline = microstripLine;component = pcbcascade(coupler,mline,3,1) creates a new component by cascading Port 3 of the coupler to Port 1 of the microstrip transmission line.

Data Types: double

'Interactive' — Interactive port selection

true | 1 | false | 0

Use interactive, set to either true, or 1 to open an interactive graphical interface to select the cascaded ports on component1 and component2.

Example: pcbcascade(component1,component2,'Interactive',true)

Data Types: logical | string

'RectangularBoard' — Create rectangular board shape

true | 1 | false | 0

Use RectangularBoard set to logical true or 1 to create a rectangular board shape.

Example: combinedcomponent = pcbcascade(component1,component2,'RectangularBoard',true)

Data Types: logical | string

'GroundFloodFill' — Create rectangular ground shape

true | 1 | false | 0

Use GroundFloodFill set to logical true or 0 to create a rectangular GroundShape. By default GroundFloodFill is true.
