Dielectric Resonator, Band Stop

Dielectric Resonator, Band Stop

Netlist Format

A dielectric resonator, bandstop instance has the following netlist format:

Axxx n1 n2 W=val D=val HD=val SDR=val ER=val L=val S=val HT=val
[HS=val ES=val] COMPONENT=dielectric_resonator_bandstop SUBSTRATE=substrate_name

n1 is the name of the node attached to the pad. The entry COMPONENT=dielectric_resonator_bandstop identifies the element. 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.

**DRBS Instance Parameters**
Parameter	Description	Unit	Default
W	Width of the MS	Meter	1e-3
D	Diameter of the DR	Meter	5e-3
HD	Height of the DR	Meter	4e-3
SDR	Conductivity of DR	mho-meter	1e-16
ER	Dielectric constant of DR	None	35.0
L	Length of reference plane to center of DR	Meter	50e-3
S	Distance between DR and MS	Meter	0.3e-3
HT	Distance between cover and the top of the DR	Meter	0.8e-3
HS	Height of the standup layer	Meter	0
ES	Dielectric constant of the standup layer	None	1

Netlist Example

Adrbs1 Port1 Port 2 W=0.5e-3 D=3.4e-3 HD=2e-3 COMPONENT=dielectric_resonator_bandstop 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. The resonator dimensions should satisfy 0.1 < D/HD < 10.
