Abstract :
A novel wideband uniplanar balanced subharmonic mixer is proposed and demonstrated. The mixer is based on the broadband tapered coplanar waveguide (CPW) DC-block filter, and the in-phase and out-of-phase T-junctions interconnected through a pair of quarter-wavelength slotlines. The fabricated subharmonic mixer has an RF bandwidth over one octave from 12 to 28 GHz with a conversion loss ranging from 8.5 to 12.5 dB.
