abstract
A balanced sampling circuit realized using step recovery and Schottky diodes on coplanar waveguide, coplanar strips, and slotlines is presented for ultra-wideband communications and radar applications. An efficient design was implemented to achieve improved performance. The impulse generator, providing signal for the sampling gate, was designed 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 9-GHz RF bandwidth with 500-MHz sampling frequency.
