rfckt.cascade class - Package: rfckt

Cascaded network

Syntax

h = rfckt.cascade h = rfckt.cascade('Property1',value1,'Property2',value2,...)

Description

Use the cascade class to represent cascaded networks of RF objects that are characterized by the components that make up the network. The following figure shows the configuration of a pair of cascaded networks.

h = rfckt.cascade returns a cascaded network object whose properties all have their default values.

h = rfckt.cascade('Property1',value1,'Property2',value2,...) returns a cascaded network object, h, based on the specified properties. Properties you do not specify retain their default values.
