Evaluation Board Design
The evaluation board is a platform for testing and interfacing design circuitry. To accommodate the
interface testing of the RI23110, the evaluation board schematic and diagrams are provided for
preliminary analysis and design. Figure 19 shows the basic schematic of the board for the 1720
MHz to 1910 MHz range. Figure 20 illustrates the board layout.
