Evaluation Board Description
The evaluation board is a platform for testing and interfacing
design circuitry. To accommodate the interface testing of the
SKY77171, the evaluation board schematic and diagram are
PA MODULE FOR WCDMA (1920-1980 MHZ)
included for preliminary analysis and design. Figure 2 shows the
basic schematic of the board for the 1920 MHz to 1980 MHz
range and Figure 3 is the assembly diagram.
