Evaluation Board Description
The SKY65052-372LF Evaluation Board is used to test the
performance of the SKY65052-372LF low noise transistor. An
assembly drawing for the Evaluation Board is shown in Figure 8.
The Evaluation Board schematic diagram is shown in Figure 9.
Table 5 provides the Bill of Materials (BOM) list for Evaluation
Board components.
Circuit Design Considerations
Input and output traces have been minimized to reduce losses. All
surface mount components are 0402-sized to reduce component
parasitics. Use of 0603 or larger components is not
recommended. Component spacing has also been minimized. The
board is provisioned with two RF connectors and a DC launch. RF
connector and board loss up to component C1 is approximately
0.1 dB at 2.4 GHz.
