Abstract :
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, are also presented with experimental results. These results show our fully monolithically integrated demonstrator performs PPM time hoping and ASK modulation schemes with respective data rate up to 500 Mbps and 1 Gbps
