Transmission Line, Electrical Length

Transmission Line, Electrical Length

Netlist Format

An instance of a transmission line with electrical length has the following netlist syntax:

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

n1 and n2 are the names of the nodes attached to the transmission line. The entry COMPONENT=TRL_E identifies the element as a transmission line with electrical length.

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

**Transmission Line with Electrical Length,**
**Instance Parameters**
Parameter	Description	Units	Default
W	Conductor width	Meter	0.001
E	Electrical length	Degree	45
F	Reference frequency for E	Hz	1e9

Netlist Example

A7 Port1 Port2 W=0.001 E=45 F=5000000000
+ COMPONENT=TRL_E SUBSTRATE=SL1

where SL1, the selected layout technology or substrate type, has a definition such as:

.SUB SL1 SL( B=0.001524 Er=4.40000000000000
+ TAND=0.0200000000000000 MET1=1.72413793103448
+ T1=1.7145e-005 RGH=0mil)

Notes

1. [Stripline] For accurate results, W/B <10.
