Abstract :
An ultra wideband (UWB) sampler, realized using step recovery and Schottky diodes on coplanar waveguide, coplanar strips and slotlines, has been developed for UWB wireless communications and radar systems. The impulse generator, providing signal for the sampling gate, was also included along with a new LO feeding structure. The fabricated circuit shows 16-19 dB conversion loss without amplifier and 1-4 dB conversion gain with amplifier across a 9-GHz RF bandwidth with 500-MHz sampling frequency.
