A Sub-harmonic Quadrature Mixer
Using APDPs for UWB Systems

This article presents an ultra-wideband (UWB) sub-harmonic mixer comprising anti-parallel diode pairs (APDP), a miniaturized bandpass filter (BPF) and a wideband 45° Wilkinson power divider. The proposed UWB mixer operates over the 3.1 to 4.8 GHz band ...
A great deal of attention has recently been paid to ultra-wideband (UWB) technologies for short-range and high data-rate wireless personal area networks (WPAN). By supporting data rates up to several hundred megabits per second (Mbps), these technologies are expected to be used in multimedia consumer electronic products in the...
