Open publisher page 3 citations

Abstract

This work presents a frequency domain ultra-wideband receiver architecture spanning from 500 MHz to 10.5 GHz. Proposed architecture uses Transform Domain (TD) sampling method which relaxes the ADC performance bottleneck for digitizing 500 MHz baseband signal. To achieve wideband operation a RF front end consisting of wideband LNA, VGA, baseband mixer and integrator is designed using UMC 130nm technology. Due to wide frequency operation this architecture is suitable for software defined radio applications.
