Evaluation Board Description
The evaluation board is a platform for testing and interfacing
design circuitry. To accommodate the interface testing of the
SKY77162, the evaluation board schematic and evaluation board
assembly diagram are included for preliminary analysis and
design. Figure 9 shows the basic schematic of the board for the
824 MHz to 849 MHz range.
