Concurrent Dual Band Six-port based Receivers: Topologies and Calibration Technique

Abstract

In this paper, two concurrent dual band architectures for six-port based receiver (SPR) are compared in terms of complexity, performance and hardware implementations. Experimental set-up of each architecture and the recovering of the two envelop signals using augmented Hammerstein model based calibration approach have been performed to illustrate the difference between the two topologies. In order to evaluate the performance of each architecture a comparative study in term of Error Vector Magnitude (EVM), spectrums and constellations has been performed.
