Direct Conversion Mixer IC for Application to Long Distance Wireless Power Transmission

In this paper, Using the silicon CMOS technology, direct conversion mixer was fabricated on silicon substrate for a realization of the long distance wireless power transmission system. The size of the mixer is 0.8 mm x 0.5 mm. The input frequency of mixer is 24 GHz, and converted BB frequency is 30 MHz. The conversion loss and output power of mixer was -9 dB and -10 dBm, respectively. Wireless energy or power transfer is the transmission of electrical energy from a power source to a power consumer without interconnecting wires.
