DATA SHEET • SKY73020-11 DOWNCONVERSION MIXER
Evaluation Board Description
The SKY73020-11 Evaluation Board is used to test the
performance of the SKY73020-11 downconversion mixer. An
assembly drawing for the Evaluation board is shown in Figure 41
and the layer detail is provided in Figure 42.
Circuit Design Considerations
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 SKY73020-11 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
