Abstract

We present a topology to provide tolerate quadrature signals in a MB-OFDM UWB frequency synthesizer. This frequency synthesizer is modified to replace a RC-CR network (RC-CR phase shifter) with a frequency division network (dual-mode divider), eliminating amplitude and phase errors of the RC-CR network. The proposed topology obtains superior suppression of image sideband of -15.5 dB when mismatches of RC passive components are assumed, based on the Monte Carlo simulation.
