In this paper, a cost-effective approach on receiver systems for frequency scanning and direction finding applications is presented. A hybrid approach on analog front-end topology is introduced, that combines direct sampling and double super-heterodyne architecture. Key modules like a reconfigurable filter, reference clock distribution units, and low noise PLL (phase-locked loop) are highlighted and the trade-off between cost effectiveness and performance is investigated. The performance of those modules is presented by measurement results.
