本人最近在学习RFID,收发芯片是MLX90121,这是手册给出的设计参考:
这是手册中的说明:
The transmitter signal is coupled with DC blocking capacitor C2 to the antenna matching network, which is
a T network made up by L2, CV1 and L1. CV1 allows a proper matching between the 50Ohm antenna
and the output impedance of the transmitter stage.
这是手册中的参数:
问题:按照此设计,我算出的阻抗不是50欧,请指教:
