Syntax

resonator = design(ringresonatorobj,frequency)
splitter = design(___,Name=Value)

Description

resonator = design(ringresonatorobj,frequency) calculates the dimensions of a ring resonator around the specified frequency.

example

splitter = design(___,Name=Value) designs a ring resonator 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

Ring resonator, specified as a resonatorRing object.

Example: resonator = resonatorRing; design(resonator,2e9) designs a ring resonator around a frequency of 2 GHz.

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

Example: 55e6

Data Types: double

Name-Value Arguments

collapse all

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 ring resonator, specified as a positive scalar in ohms.

Data Types: double

Output Arguments

collapse all

Ring resonator operating around the specified frequency, returned as a resontorRing object.
