ADRV9371-N is supposed to match the 1.8-2.6GHz frequency range. when connecting to a standard 2GHz antenna the matching in the specified range decreases dramatically and highest gain/matching is found at ~3GHz instead.
I need to resolve the matching issue and get maximal gain at the frequency range for which the board is specified.
In addition I need to put an external RX LNA to get similar gain (or at least signal levels) as I used to get with AD9361.
I would like to understand which external components I need to be able to connect to a RX antenna.
please advise on both issues.
