M24LR series internal capacitance considerations

for antenna tuning

1

Introduction

conditions, more considerations have to be taken into account for tuning the antenna in an

real application environment. This document describes the M24LR series tuning

capacitance variation as a function of input voltage, explains the M24LR series tuning

capacitance specification and gives a robust tuning capacitance target for the inductive loop

antenna design.

has been used hereafter for specific measurements purpose.
