ABSTRACT
The article explores the trade-offs involved with a number of different radio frequency front-end topologies for software radios. The most common types of radio frequency front-ends for software radios include dual conversion, single conversion and tuned radio frequency receivers. It is stated that the suitability of a particular receiver topology depends on its sensitivity, selectivity, stability, dynamic range and spurious response. It is pointed out that the designer needs to weigh the multitude of combinations before arriving at the optimal design, and added that the trade-off occurs between sensitivity and selectivity.
