Abstract :
This letter presents analysis and design considerations for lumped (inductor and capacitor) matching networks operating at high efficiency (>95%). Formulas for calculating matching network efficiency are given, and it is shown that efficiency can be expressed as a function of inductor quality factor QL, capacitor quality factor QC , and transformation ratio. These formulas are used to evaluate the optimum number of L-section matching stages as a function of conversion ratio. Both simulation and experimental results are presented that validate the analytical formulation
