Bend, Unmitered

Bend, Unmitered

Netlist Form

Axxxx n1 n2 W1=val W2=val [NSUM=val]
COMPONENT=unmitered_bend SUBSTRATE=substrate_name

n1 and n2 are the names of the nodes attached to the unmitered bend. The entry COMPONENT=unmitered_bend identifies the element as an unmitered bend. The entry SUBSTRATE=substrate_name identifies the microstrip substrate model name selected for the design (see Selecting a Microstrip Substrate). See the Microstrip (MS) Substrate for information on this substrate type.

**Unmitered Bend Instance Parameters**
Parameter	Description	Unit	Default
W1	Width of line 1	Meter	0.001
W2	Width of line 2	Meter	0.001
NSUM	Number of modes considered in the field expansion	None	3

Netlist Example

Abend1 1 2 W1=3e-4 W2=5e-3 NSUM=3
+ COMPONENT=unmitered_bend SUBSTRATE=FR4

where FR4, the selected layout technology or substrate type, has a definition such as:

.SUB FR4 MS( H=7.6200e-004 Er=4.4 TAND=0.02 TANM=0
+ MSat=0 MRem=0 HU=0.00508 MET1=1.72413793103448
+ T1=1.7145e-005 RGH=0mil)

Notes

1. [All substrates] This element refers to a right angle bend, where the two intersecting lines can be defined with different widths. The outer corner of the bend is not mitered.

2. [All substrates] Reference planes coincide with the inside vertex of the corner.

3. [Microstrip] Radiation loss is included if a cover is not specified in the substrate definition.
