we noted in Section 2.5, the power amplifier designis based on a Melexis application note ([Mel04]), recallFigure 3. We used the output stage of the TI S4100 readermodule in the base board to drive the power amplifier in-put. We did not invest any effort in impedance matchingsince the power amplifier input is voltage driven. Wemanufactured the PCB for the power amplifier using thesame technique as used for the base board, and with thesame low cost DC ripple filter (recall Figure 6) to main-tain a low noise fi[login to view URL] the Melexis design, empirical results led usto connect a filter comprised of R2 and C4 at the out-put (See Figure 3). This filter reduces the Q of the out-put impedance matching filter, enabling fine tuning ofthe output signal phase. We discovered that the filter in-creased the read range signifi[login to view URL] output voltage amplitude of the power
