DOI: 10.1109/tcsii.2019.2937654
Abstract: Due to the use of wide-band analog front-ends in order to cover the many different frequency bands used in Long Term Evolution (LTE), blocker signals received by the antenna may reach the mixer input. As… read more here.

DOI: 10.1109/tvlsi.2017.2695719
Abstract: A 0.9–5.8-GHz receiver RF front-end (RFE) integrating a dual-band low-noise transconductance amplifier (LNTA), a passive harmonic-rejection (HR) down-conversion mixer, and an all-digital frequency synthesizer for software-defined radios are presented. A switchable three-coil transformer acting as… read more here.
