Based on the geometry relationship of the conventional dual-mode ring resonators, this study concisely describes the operation principle of a kind of dual-mode resonator filters with in-line feed-lines. The investigated filter topology is fed by two pairs of orthogonal branch lines and can realize in-line configuration for the input and output (I/O ...

2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019
In this paper, based on mixed electronic and magnetic coupling (E-M coupling) structures and miniaturized resonator units, a compact low-temperature co-fired ceramic (LTCC) bandpass filter at 2.48 GHz is proposed. Due to the E-M coupling and source-loading structures, three transmission zeros (TZs) are introduced.

New S-Band Bandpass Filter (BPF) With Wideband Passband for Wireless Communication Systems
IEEE Microwave and Wireless Components Letters, 2012In this letter, a new wideband bandpass filter (BPF) using microstrip parallel-coupled line structure for s-band applications is proposed. The filter is constructed of two sections of three coupled lines separated by a nonuniform line resonator. In order to introduce one transmission zero at each edge of the desired passband, one of the outer coupled ...
