AFE7900EVM: AFE7900EVM

Part Number: AFE7900EVM

Tool/software: 

Good morning everyone.
I recently purchased an afe7900 evaluation board.
This card uses different balun models, both in tx and rx,  to work in different bands.
I would like to know if it was possible to replace all the baluns (6 in RX and 4 in TX) 
to be able to work only on the 5 to 6 GHz frequency band. 
What baluns/transformers could I use? I also wanted to know if there is a model of AFE79XX that covers this band (5-6 Ghz) on all channels.

Regards, Luca.

    SOLVED!

    The AFE7950EVM development board seems to have the features I need.
I have currently given up on the idea of ​​replacing the baluns on the AFE7900EVM, 
    but have decided to purchase a brand new AFE7950EVM.

    Hi Luca,

    The AFE7900EVM has different matches, with different baluns, to cover bands for all customers. Unfortunately there is not a balun that could fit on all channels as the footprints would not be compatible. 

    We recommend using the channel that is matched for your band of interest.

    Regards,
