Q.

Is the performance of the AD8348 and ADL5387 maintained at low frequencies below the 50 MHz as specified on the datasheet?

 

----------------------------------------------------------------------------------------------------------------

A.

The LO path on both the AD8348 and ADL5387 are DC coupled and because of this performance should be maintained as specified on the datasheet to below 1 MHz with a square wave LO.  It is important to input a square wave LO for the fast rise and fall times.
