摘要：

The successful use of the Design of Experiments (DOE) and Response Surface Methods (RSM) approaches in the simultaneous optimization of geometrical parameters and power requirements of a 24 GHz mixer is presented. The benchmarking geometry is a low-cost mixer for a Doppler Radar Sensor, built in Liquid Crystal Polymer (LCP) technology. First, the single-balanced diode mixer is designed for good RF/LO isolation and low conversion loss. The structure is then optimized using the same experiment that integrates both geometrical parameters and the LO input power levels. The optimized mixer shows a 4.5 dB conversion loss with a 23 dB isolation between RF and LO ports at the operating input power levels, the best reported so far for this frequency range and in these operating conditions.
