Abstract :
Concurrent transmission and reception of RF signals in different frequency bands is required for transceivers in IMT-Advanced systems to support the spectrum aggregation technique. In this paper, we introduce a prototype of concurrent dual-band receiver that uses IF undersampling, and present some evaluation results. The prototype has two types of receiver architecture, one a single mixer-type receiver that has a common IF (intermediate frequency) stage where the RF signals are converted, and the other a quadrature mixer-type receiver that has a common complex IF stage. Evaluations show that both receivers function adequately as concurrent receivers and that the quadrature mixer-type receiver gives better waveform quality than the single mixer-type receiver.
