1. Millimeter-wave Transceiver ICs for Ultrahigh Data Rate Communications Using Advanced III-V and Silicon Technologies
Abstract : Today’s main driving parameter for radio transceiver research is the ability to provide high capacity while maintaining low cost, small form factor, and low power consumption. Direct conversion architectures (due to the feasibility of monolithic integration) at millimeter-wave (due to wideband availability) have attracted large interest in recent years because of their potential to meet these demands.

5. Non-galvanic Interconnects for Millimeter-wave Systems
Abstract : Fueled by the increasing demand for higher data rates, millimeter-wave (mmW) systems emerged as a candidate that can provide multi-gigabit per second (Gb/s) transmission. This demand is mainly driven by modern communication systems and several other wireless and sensing applications such as production quality inspection and imaging systems. READ MORE
