Low Loss W-Band Packaged Filtering Balun Based on a Modified Quarter-Mode Folded Substrate-Integrated Waveguide Cavity

open access: yesIEEE Access, 2022
A novel packaged filtering balun is proposed by modifying quarter-mode edge and diagonally folded SIW (FSIW) cavities. The TM220 mode is selected to realize the differential signal conversion by using a quarter-mode diagonally FSIW.
