I'm using AD-FMCOMMS2 with Xilinx AC701. On the RX path, I noticed that only a capacitor is used on each differential path. I noticed that the signal power dropped 11~12dB after Balun. Theoretically, it should be about 3dB. Is this lardge signal power dropping expected. I'm using 2.4GHz band. Thanks.
