This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5–18 GHz frequency bandwidth. Experimental results validate the performance of such a modulator over more than a frequency decade.
A 140GHz fully-integrated wireless chip-to-chip solution using a QPSK self-heterodyne topology is demonstrated for short range and low power communication. Implemented in 0.13μm SiGe∶C BiCMOS technology, the Tx and Rx silicon area including dipole antennas is 0.31mm2. This transceiver achieves a data rate of 10Gbps at a free air distance of 0.6mm with a Error Vector Magnitude equal to 27 %.
This paper presents a new topology of data coding and data broadcasting exclusively sent to a specific location area. The proposed technique exploits specifically different received signals to focus energy and to rebuild information intelligibly only for a chosen position. By this way, the receiver coordinates become its own “key” to decode the transmitted data. The overall topology uses multiple...
This paper presents the performance of a millimeter wave (MMW) positioning system operating in indoor environment and using broadband impulse signals. The main original contribution is an approach based on a focusing technique to minimize the performance degradations due to the multipath propagation. Experimental results validate the ability of the topology to perform multi-laterations based on a...
A direct conversion demodulator at 60GHz based on Gilbert cells down-converter is presented in this paper. The OOK modulation allows using a single detector on receiver side to discriminate the 0 or 1 data. The conventional diode based detector presents conversion losses and obviously a high noise figure. Derived from the classic Gilbert cell mixer the demodulator presents a conversion gain of 9.7dB,...
