... ADL5350 2. Tune the LO port input network for optimum return loss. Typically, a band-pass network is used to pass the LO signal to the LOIN pin recommended to block high frequency harmonics of the LO from the mixer core. LO harmonics cause higher RF frequency images to be downconverted to the desired IF frequency and result in a sensitivity degradation. If the ...
