Abstract:
This paper presents a novel power divider with filtering responses. By using quarter-wavelength resonators with a novel feeding structure, both power division and bandpass responses are obtained, and compact size is realized. Discriminating coupling is utilized to suppress the third harmonic to obtain wide stopband. The isolation resistor is connected at two ends of the input feed line, and good isolation is obtained. Two transmission zeros are generated at two edges of the passband, resulting in high selectivity. For demonstration, a filtering power divider is implemented. Comparisons of the measured and simulated results are presented to verify the theoretical predications.
