Evaluation Board Description
The SKY73032 Evaluation Board is used to test the performance
of the SKY73032 downconversion mixer. An assembly drawing for
the Evaluation Board is shown in Figure 3 and the layer detail is
provided in Figure 4.
Circuit Design Configurations
The following design considerations are general in nature and
must be followed regardless of final use or configuration:
1. Paths to ground should be made as short and as low
2. The ground pad of the SKY73032 provides critical electrical

and thermal functionality. This pad is the main thermal
conduit for heat dissipation. Since the circuit board acts as
the heat sink, it must shunt as much heat as possible from
the device. Therefore, design the connection to the ground
