design

Design coupled microstrip transmission line around particular frequency

Syntax

cline = design(clineobj,frequency)

cline = design(___,Name=Value)

Description

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

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

Design Coupled Microstrip Transmission Line Around 1.8 GHz

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

clineobj — Coupled microstrip transmission line

coupledMicrostripLine object

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.

frequency — Design frequency of transmission line

real positive scalar

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

Z0e — Even mode impedance

52 (default) | positive scalar

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

Data Types: double

Z0o — Odd mode impedance

48 (default) | positive scalar

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

Data Types: double

Output Arguments

cline — Coupled microstrip transmission line operating around specified frequency
