Design coupled microstrip transmission line around particular frequency

Description

cline = design(clineobj,frequency) designs a coupled microstrip transmission line around the specified frequency.

example

cline = design(___,Name=Value) designs a coupled microstrip transmission 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.

Examples

collapse all

Design a coupled microstrip line at 1.8 GHz with an even mode impedance of 60 ohms.

 cline = design(coupledMicrostripLine,1.8e9,Z0e=60);
 show(cline);

Plot the S-parameters of the transmission line.

spar = sparameters(cline,1.8e9);
rfplot(spar)

Input Arguments

collapse all

Coupled microstrip transmission line, specified as a coupledMicrostripLine object.

Example: cline = coupledMicrostripLine; design(cline,2e9) designs a coupled microstrip transmission line around a frequency of 2 GHz.

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

Example: 2e9

Data Types: double

Name-Value Arguments

Example: Z0e=45

Even mode impedance of the transmission line, specified as a positive scalar in ohms.

Data Types: double

Odd mode impedance of the transmission line, specified as a positive scalar in ohms.

Data Types: double

Output Arguments
