Abstract: This application note explains how an RF DAC like the MAX5879 is an essential component for a direct RFradio transmitter. The application note summarizes the RF transmitter architectures of zero-IF, complex IF, high (real) IF,and direct RF before detailing the benefits of the direct RF transmitter for wireless applications, which have increasedwith the rise in smartphone and tablet computer use. As the application note shows, the superiority of a direct RFarchitecture with a high-performance DAC results in reduced component count and lower power dissipation whilesynthesizing very wideband signals.
