Cross

Cross

Netlist Format

An instance of a symmetric coplanar waveguide cross has the following netlist syntax:

Axxx n1 n2 n3 n4 [W1=val] [W3=val][Y=val] COMPONENT=cpwcross SUBSTRATE=substrate_name

n1, n2, n3, and n4 are the names of the nodes attached to the cross.

The implementation of the coplanar waveguide cross element requires the element to be symmetric. Only widths W1 and W3 are specified, with W2=W1and W4=W3.

The entry COMPONENT=cpwcross identifies the element as a coplanar waveguide cross element.

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

**Coplanar Waveguide Cross Instance Parameters**
Parameter	Description	Units	Default
Y	Ground-to-ground spacing at all ports. Must be greater than both W1 and W3.	Meter	3e-3
W1	Conductor width at ports 1 and 2	Meter	1e-3
W3	Conductor width at ports 3 and 4	Meter	1e-3

Netlist Example

A23 Port1 Port2 Port3 Port4 W1=4.0e-004 W3=2.0e-4 Y=6.0e-4
+ COMPONENT=CPWCROSS 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 ground-to-ground distance Y is the same at all ports.

2. W1 = W2 and W3 = W4.

3. For accurate results, the substrate definition should specify:
2 < ER <14, H > Y
0.1 < Wn/Y <0.9, where Wn is the conductor width at any port.

4. The coplanar mode is assumed to exist only. Parasitic effects due to air bridges are not considered by this model.
