Syntax

coupler = design(couplerobj,frequency)
coupler = design(___,Name,Value)

Description

coupler = design(couplerobj,frequency) designs a two or three-section wideband branchline coupler around the specified frequency.

example

coupler = design(___,Name,Value) designs a wideband branchline coupler line with additional options specified using name-value arguments.

Note

PCB components designed using the design function operate around the specified frequency with a 10-15% tolerance.

Input Arguments

collapse all

Wideband branchline coupler, specified as a couplerBranchlineWideband object.

Example: coupler = couplerBranchlineWideband; design(coupler,2e9) designs a wideband branchline coupler around a frequency of 2 GHz.

Design frequency of the coupler, specified as a real positive scalar in hertz.

Example: 3e9

Data Types: double

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: Z0=70

Characteristic impedance of the coupler, specified as a positive scalar in ohms.

Data Types: double

Output Arguments

collapse all

Wideband branchline coupler operating around the specified frequency, returned as a couplreBranchlineWideband object.
