A 6-10 GHz FM-UWB Transmitter

An integrated FM-UWB transmitter with an off-chip antenna is presented in this paper. The proposed transmitter operates at the upper UWB frequency range, starting from 6GHz to 10GHz. It consists of a ring oscillator to generate the FM signal, a switching mode power amplifier that flattens the transmitter spectrum and a fractal based monopole antenna. The oscillator and the power amplifier are designed using UMC130 nm CMOS process with 1.2V power supply and 3.3mW total power consumption. The proposed antenna is fabricated on a low-cost FR4 substrate with a good agreement between measured and simulated results.
