In the datasheet of ADL5350 mixer network it is suggested to use external Filter modules at the IF, RF and LO ports.
The filter at the LO port is acceptable, but we have a very high bandwidth systems (40 MHz) and hence we cannot add filter networks at IF and RF ports as they may give varied response over entire range. So what is this the solution for this issue?
In other Mixer modules like ADL5801, there is no suggestion to add any filter networks. Are these Mixers internally tuned ?
