    Digital Beamforming, the power efficient solution for mobile devices!

    We have in our previous posts shown the advantages with digital beamforming over analog beamforming from a performance point of view. Then one may ask; why hasn’t digital beamforming in mobile devices happened yet? Well, if you ask people in the field, they will say that a digital approach has way to high power consumption…

    mmWave Radio design for mobile devices

    Chips today for consumer electronics are practically all done using a technology known as CMOS (Complementary Metal Oxide Semiconductor, silica-based). However, for the high frequency parts in a radio transceiver which are present in all communication devices,  another technology based on gallium compounds has been considered better suited in terms of high frequency performance. However,…
