Model Description
CAP-AVX-GX02-001 is a substrate scalable model for the AVX GX02ZZ104MAT2 (0.1uF) ultra broad band
capacitor. The model is for use with microstrip applications and accounts for substrate (or printed circuit
board) related parasitic effects. Substrate height, dielectric constant, loss tangent, interconnect metal thickness, component tolerance, pad width, pad length, and pad gap are model input parameters. Effective series resistance (ESR) was measured to 1GHz and incorporated into the model. A Sim_mode switch allows
pad stack effects to be disabled. This model has been validated to 65 GHz on a 5 mil Alumina substrate,
and to lower frequencies using additional printed circuit board materials (see Technical Notes).

Technical Notes
PC Board Footprint
• Two–port S-parameters measured using a vector network

analyzer and on-board probing with calibration referenced
to the outside edges of the component pad stack.
• Capacitors measured in a series microstrip configuration.
Models for alternative interconnect configurations (e.g.
coplanar waveguide) are available upon request.
• Substrates used to extract the models: 4 mil Rogers
4350B, 60mil Rogers 4003 and 5 mil Alumina.
• Typical range of valid substrate types (substrate height H
in mils and dielectric constant Er): 0.5 ≤ H/Er ≤ 16.6.
Reference Planes
• Highest frequency for measurement validation: 8 GHz (60
mil RO4003), 30 GHz (4 mil RO4350B) and 65GHz (5
