A sub-harmonic quadrature mixer using APDPs for UWB systems

초록

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 degrees Wilkinson power divider The proposed UWB mixer operates over the 3.1 to 4.8 GHz. band and offers excellent conversion loss, linearity, and phase and amplitude balances for quadrature outputs.
