The design and analysis of a LO/RF and LO/IF isolation and conversion loss in a single balanced diode mixer are presented in this paper. The single balanced diode mixer is realized by using a configuration of a 90 degree hybrid coupler and two HSMS282C GaAs Schottky diodes. A single balanced diode mixer with band pass filter is one of common devices used in(More)
As a replacement to existing fossil fuels, biofuels, have proven their worth; however, their widespread use is limited due to inconsistent yields, higher costs and poor productivity. An oleaginous yeast, Rhodosporidium toruloides has been reported to accumulate substantial amounts of lipids (that can be converted to biofuels) and therefore, it was selected(More)
The expected operating scenarios of 5G pose a great challenge to orthogonal frequency division multiplexing (OFDM) which has poor out of band (OoB) spectral properties, stringent synchronization requirements, and large symbol duration. Generalized frequency division multiplexing (GFDM) which is the focus of this work, has been suggested in the literature as(More)
Satellite based 'Automatic Identification System' (AIS) for global maritime applications is being highly investigated in recent years. A receiver of such a system receives simultaneous transmissions from different self organized areas, which may lead to collision of information received at satellite; thereby reduce the scope of detection. In this paper we(More)
