Nexxim Simulator > Lange Coupler, Electrical Length
Netlist FormatA 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 ExampleASSLANGE1 net1 Port2 net3 Port4 N=4 W=1e-3 S=.2e-3
E=75 where SS1, the selected layout technology or substrate type, has a definition such as: .SUB SS1 SS ( Notes1. 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).
