Measurement Uncertainty in Nonlinear Behavioural Models of Microwave Devices

Introduction

DUE JUNE!

• Sell the project
• Wireless is the backbone of modern civilisation
• Nonlinear amplifiers are vital for an energy efficient future
• Cheaper
• Instrumentation outpaced metrology
• Design depends on modeling, models are characterised by measurements.
• Modeling depends on metrology
• Modeling and metrology include error
• Valuable to quantify contributions
• Measurement uncertainty evaluation enables this

Microwave Measurements

• Wave parameters
• Scattering parameters as a linear model
• VNAs
• NVNAs

Measurement Uncertainty

GUM paper Published in Elsevier Measurement

• Brief NPLesque spiel - "underpinning" etc
• Enables comparisons
• Many interprations possible
• GUM is international guide which aims to standardise and enable compatible and fairer comparisons
• Even GUM changes - frequentist vs Bayesian
• Elsevier paper

Microwave Measurement Uncertainty

Ripple paper Published in IET MAP

• Calibration and residual error in VNAs

Nonlinear Behavioural Modelling

XP extraction options paper Abstract written

• Direct waveform lookup
• X-Parameter model
• Cardiff model
