Hello,
I am using CC2640, in differential external bias mode so that it can feed 5 dBm power to antenna. But when I measured conducted power using power meter It showed -25 dBm. I think there is loss in balun and pi network as i have not designed. I just copied it from TI reference design. Please let me know procedure to design Balun network. If any guideline is available please share it.
What is differential output impedance of CC2640F128RHB.
