I need a circuit which allows the multiplication of two high frequency data signals (up to 1 GHz). Is the ADL5391-EVALZ able to handle this? Do I have to make any changes at the circuit before starting (e.g. remove resistors, capacitors,…) or is the evaluation board ready to use out of the box?
The idea is:
Supply +5V to the board, set the first signal to XP, second to YP and get the output at WP, correct?
Thanks a lot!
Kind regards, Sam
That should work in principle.
I'm a little concerned outputs not being terminated in a balance fashion. Why don't you just connect the W output of the bottom ADL5391 fully differentially to the Z input of the top ADL5391? So just amend the connection with Wp to Zn.
Also, I would take the W output of the top ADL5391 through a balun or differential-to-single ended amplifier, instead of just taking the Wp output.
