In this paper we demonstrate that it is possible to communicate over 10s of metres with systems that can also be powered by the interrogating beam. Low communications energies of 16pJ/bit/mm2 of modulator are achieved, and it should be possible to reduce these further. The total electrical power consumption of the mote is approximately 40nW.

In this paper, an even harmonic mixer and a simple switching mixer are discussed first. And a novel even harmonic switching mixer with DC offset free and low noise figure, especially for the direct conversion application, is proposed.

A single-feed ICPA realised on a cavity-down CBGA package of 15 15 1.9mm3 has been proposed for use in highly integrated concurrent dual-band wireless receivers operating at 2.4 and 5.25 GHz. The ICPA offers the possibility to combine antennas and highly integrated wireless receivers into standard surface mounted devices, and thus, enjoy economical advantages of mass production and automatic assembly.
