Lange Coupler, Electrical Length

Lange Coupler, Electrical Length

Netlist Format

A Lange coupler, electrical length instance has the following netlist format:

ACPWLANGExxx n1 n2 n3 n4 N=4 W=val S=val E=val F=val
WF=val GF=val WA=val HA=val SO=val
COMPONENT=cpwlange_electrical SUBSTRATE=substrate_name

n1, n2, n3, and n4 are the names of the nodes attached to the coupler. The entry COMPONENT=cpwlange_electrical identifies the element.

The SUBSTRATE=substrate_name is the coplanar waveguide substrate model name selected for the design (see Selecting a Coplanar Waveguide Substrate for details).

**Lange Coupler, Electrical Length Instance Parameters**
Parameter	Description	Unit	Default
N	Number of lines. Must be 4.	None	4
W	Conductor width	Meter	1e-3
S	Conductor spacing	Meter	1e-3
E	Electrical length	Degree	90
F	Frequency at which E is taken	Hz	1e9
WF	Center conductor width of feeding lines	Meter	0.5e-3
GF	Slot width of feeding lines	Meter	0.5e-3
WA	Width of air bridges	Meter	0.1e-3
HA	Height of air bridges	Meter	0.1e-3
SO	Distance to ground plane	Meter	1e-3

Netlist Example

ACPWLANGE1 Port1 Port2 Port3 Port4 N=4 W=1e-3 S=.2e-3 E=75
+ COMPONENT=cpwlange_electrical SUBSTRATE=CPW1

where CPW1, the selected layout technology or substrate type, has a definition such as:

.SUB CPW1 CPW(
+ H=0.001524 Er=4.4 TAND=0.02 HU=2.54E-4 HL=2.54e-4
+ MET1=1.724137931034483 T1=2.54e-5 RGH=0)

Notes

1. The conductor width of all fingers is W. The diatance between all fingers is S.

2. The number of fingers, N, must be 4.

3. Port 1 is the input port, port 2 is the coupled port, port 3 is the through port, and port 4 is the isolated port.

4. The length of air bridges used to approximate their parasitic effects, is 2*(W+S).
