Link Budget Analysis in the Sdr Analog Baseband Section
In a direct conversion receiver, the analog baseband section is responsible for adjacent channel selectivity, anti-aliasing filtering and dynamic range maximization. In the context of SDR, the analog circuits part of it are subjected to variable specifications: their requirements include the dynamic range and the Signal to Noise Ratio for the ADC and Automatic Gain Control, selectivity, noise, and linearity for the channel-select filter. This chapter discusses these specifications for a multimode reconfigurable SDR front end. The reference radio architecture is a flexible zero-IF transceiver (Section 2.3). A discussion is carried on the optimal specifications aiming at the receiver power minimization.
