13.56 mhz receiver
Hi all. I wish I had found this forum a little sooner.
I'm trying to design a RF power amplifier to work at 13.56Mhz. I'm trying to amplify the transmit power from a Texas Instrument TRF7960 reader IC. I want an output power of 8 Watts to power up an antenna that I have built. Reason for this much power is we want to be able to achieve a read range of 1meter. I'm stuck on the power ampflier. Whatever i've designed is not giving me any gain. but a loss. I have simulated my design and it gives me a gain of 9, however when built on a breadboard I'm not getting what is desired.
Some input would be appreciated. attached is a design schematic
thanks.
