A compact narrow-band low temperature co-fíred ceramic (LTCC) filter with a fractional bandwidth of 3% is proposed. The proposed filter consists of five cascaded half-wavelength resonators vertically arrayed on each LTCC layer. End-coupling between adjacent resonators is precisely controlled by rectangle-shaped slot on intermediate ground layer. The overall size of the filter is only 8 × 6 × 0.89...

A differential power divider based on the Defected Ground Structure (DGS) operating at S-Band is developed. A novel DGS structure is proposed and its performance in the power divider is analyzed using a 3D full-wave simulator. The DGS structure can eminently realize miniaturization by comparing the operating frequency with the one without DGS and the one using conventional DGS. The return loss of...
A full-wave bridge rectifier with high conversion efficiency and high input range is proposed. A power dividing network is used to handle the low reverse breakdown voltage of Schottky diodes to achieve high input power. The defected ground structure is used to increase the coupling coefficient of the power-dividing network. The power-dividing network couple the input RF power into four differential-type...
