Lange Coupler, Electrical Length

 

[spacer]

 

[spacer]

Netlist Format

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

ASSLANGExxx n1 n2 n3 n4 N=4 W=val S=val E=val F=val WF=val WA=val HA=val COMPONENT=sslange_electrical SUBSTRATE=substrate_name

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

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

Netlist Example

ASSLANGE1 net1 Port2 net3 Port4 N=4 W=1e-3 S=.2e-3 E=75
+ COMPONENT=sslange_electrical SUBSTRATE=SS1

where SS1, the selected layout technology or substrate type, has a definition such as:

.SUB SS1 SS (
+ Er=4.4 H=0.5e-3 HU=2.54e-003
+ MET1=1.7241379 T1=2.5400e-005
+ 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).
