Figure 5.1 show the transmitter block diagram. As explained in Chapter 2, the I and Q baseband signals are first upconverted to 800 MHz and then added together. In the second mixer, the result is upconverted from 800 MHz to 2.4 GHz. After two upconversions, the RF signal is applied to a power amplifier (PA) to drive the antenna. In this chapter, we describe the design of the transmitter building blocks.
