Coupled Lines, Physical Length

Coupled Lines, Physical Length

Netlist Form

An ideal coupled line, physical length instance has the following netlist syntax:

Axxx n1 n4 n2 n3 [P=val] [ZE=val] [ZO=val]
[KE=val] [KO=val] [AE=val] [AO=val] [F=val]
COMPONENT=cpl

n1 and n2 are the names of the input nodes. n4 and n3 are the corresponding output nodes. The entry COMPONENT=cpl identifies the element as an ideal coupled line, physical length.

**Ideal Coupled Line, Physical Length,**
**Instance Parameters**
Parameter	Description	Units	Default
P	Physical length	Meter	1e-2
ZE	Even mode impedance	Ohm	50
ZO	Odd mode impedance (the second character is the letter O, not the numeral zero)	Ohm	50
KE	Even mode effective dielectric constant		1
KO	Odd mode effective dielectric constant (the second character is the letter O, not the numeral zero)		1
AE	Even mode attenuation	dB/m	0.0
AO	Odd mode attenuation (the second character is the letter O, not the numeral zero)	dB/m	0.0
F	Reference frequency for AE and AO	Hertz	1e9

Netlist Example

A3 Port1 Port4 net_27 0 P=0.015
+ KE=1.12 KO=1.01 AE=0.1 F=1.25e9
+ COMPONENT=cpl
