Hello mhennerich,
Iam using AD-FMCOMMS5-EBZ + XILLINX zc706 in order to transmit an LTE 20MHz signal.
My problem is that the signal is very poor in terms of power and i want to increase the TX_output power.
Do you have any idea what changes should i do in the main.c ( ) in order to increase the gain.

In your previous post you mention that the solution is to switch to  manual gain control mode (MGC) and increase the gain until you can decode the signal. How can i increase the gain?


Thank you,

Attached you may find an image of the transmitted signal with the TX_OUPUT POWER (between -40 and -45dBm)
