hi, the following is the schematic of my design.

the PMA-5451-OUT is the LNA output through  a 0.1uF capacity.  I test power at ETC1-1-13 pin5 use spectrum. the power is 0 dBm, but the power at ETC1-1-13 pin 1 is -8  dBm, the power at pin 3 is also -8dBm, I think it should around -3 dBm

Could  you give me some advice?

Thank you
