Abstract :
A novel miniaturized uniplanar singly-balanced diode mixer is proposed based on a compact multifunction transition structure. By the independence of the coplanar-wavguide (CPW) mode and the coupled-slotline (CSL) mode, a novel compact transition which converts the CPW mode into the CSL mode is realized. This transition structure also has the functions of 180 hybrid, diplexer, and quarter-wavelength transformer, thus the size of the proposed mixer is drastically reduced. In this study, a 1~4.5 GHz uniplanar singly-balanced diode mixer is designed and fabricated on the printed circuit board, with a size much smaller than that of the conventional mixers.
