filterCoupledLine
Description
Use the filterCoupledLine
object to create a coupled line filter
in microstrip form. The filter structure consists of open-circuited coupled microstrip lines.
You can control the bandwidth of the filter by varying the filter order, width, and distance
between the coupled lines.
Creation
Description
filter = filterCoupledLine
creates a default coupled line
filter with default passband of the filter centered around 2 GHz.
filter = filterCoupledLine(
sets Properties using one or more
name-value arguments. For example, Name=Value
)filterCoupledLine(FilterOrder=5)
creates a fifth-order coupled line filter. Properties not specified retain their default
values.
