APPLICATIO S I FOR ATIO
LT5528
Additionally, the exposed pad provides heat sinking for the
part and minimizes the possibility of the chip overheating.
If improved LO and Image suppression are required, an LO
feed-through calibration and an Image suppression calibra-
tion can be performed. The evaluation board schematic
