  • Page 3: Demonstration Kit Configuration Options

    DAC Component The TSW3003 Demo Kit is built for the DAC5687, although this Demo Kit can also support the DAC5686 because the two devices are pin compatible. The procedures outlined in this document are primarily suited for the DAC5687, but can be modified easily for the DAC5686 if desired.

  • Page 4: Block Diagrams

    System Block Diagram The basic radio system block diagram in Figure 1 demonstrates where the TSW3003 Demo Kit fits in the overall transceiver. The dash-line box illustrates the components found on the TSW3003 Demo Kit board. 0° Modulator 90° Diplexer Demod Figure 1.

    WCDMA Output Power Versus ACPR Performance The ACPR has some dependency on the output power of the TSW3003. The RF output spectrum shows some IMD effects as the output power of the DAC is increased. The optimum ACPR performance occurs when there is approximately a -6dB attenuation pad between the DAC output and the TRF3703 input.

  • Page 29: Filter Specifications

    Filter Specifications 10.1 Baseband Filter The TSW3003 Demo Kit layout provides the opportunity to place components to realize up to a 5 order LC filter. The Demo Kit is by default populated with a resistive network to provide some attenuation and a two-inductor network to compensate for the droop caused by the parasitic board capacitance.

  • Page 30: Bill Of Materials And Schematics

    Bill of Materials and Schematics 10.1.1 RF Filter/Output Match The TSW3003 Demo Kit layout also provides the opportunity to place a small 3 order LC filter on the output of the modulator for either filtering or impedance matching purposes. This filter has been disabled by removing the shunt elements.
