• Description: High Gain and Linearity Diversity Downconversion Mixer
• Manufacturer: Skyworks Solutions

Evaluation Board Description
The SKY73023 Evaluation Board is used to test the performance
of the SKY73023 downconversion mixer. An assembly drawing for
the Evaluation Board is shown in Figure 3 and the layer detail is
provided in Figure 4. A schematic diagram for the SKY73023
Evaluation Board is shown in Figure 5.
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 SKY73023 provides critical electrical

impedance as possible.
and thermal functionality. This pad is the main thermal
conduit for heat dissipation. Since the circuit board acts as

the device. Therefore, design the connection to the ground
pad to dissipate the maximum heat produced by the circuit
board. For more information on soldering the SKY73023, refer
