A new simple architecture of transceiver using Impulse Radio Ultra Wide Band (IR-UWB) technique in the millimeter wave (MMW) range suited for Wireless Sensor Networks (WSNs) is presented. Two integrated transmitters have been designed in a commercial 0.1μm, 100 GHz ft GaAs pHEMT MMIC process. In order to reduce the power consumption, the first IR-UWB 60 GHz transmitter involves a negative differential...
A simple but efficient architecture based on up-conversion of impulse radio (IR) signals at 55 GHz is presented. This complete architecture has been designed using a pHEMT foundry process (ft =100 GHz). Key results on mm-waves devices-VCO, frequency doubler, RF switch, LNA and RF detector-are presented and discussed. Baseband devices, composed of a pulse generator and a sample-and-hold amplifier,...
Two simple and compact ultra-wideband, ultra-short-pulse transmitters have been developed using a monolithic microwave integrated circuit (MMIC). These pulse generators include a digital approach for the pulse forming based on a logic gate. They produce pulses with a variable width as low as 65 ps and rise and fall time about 25 ps (measured). The pulse position modulation (PPM) with pulse frequency...
