RF Attenuator Linearization Circuits

This chapter discusses the challenges associated with designing low-power receivers with large dynamic range suitable for use in mobile TV applications. It also proposes techniques to achieve a highly-linear front-end circuit with low noise figure at sensitivity. Such a front-end would be suitable for cellular phone environments that require small, low-cost, low-power components. A silicon prototype of the described solution supported with measurement results is given to demonstrate the concept.
