Shorted Stub, Electrical Length with Reference

 

[spacer]

 

 

Netlist Format

An instance of a shorted stub, electrical length with reference has the following netlist syntax:

Axxx n1 n2 W=val E=val F=val COMPONENT=shorted_stub_electrical SUBSTRATE=substrate_name

n1 is the name of the node attached to the shorted stub. n2 is the reference node. The entry COMPONENT=shorted_stub_electrical identifies the element as a shorted stub, electrical length with or without a reference node.

The entry SUBSTRATE=substrate_name identifies the microstrip substrate model name selected for the design (see Selecting a Microstrip Substrate). See the Microstrip (MS) Substrate for information on this substrate type.
