Abstract
A novel hybrid bandpass filter (BPF) with wideband and high selectivity is proposed in this paper. The hybrid BPF is composed of two film bulk acoustic resonator (FBAR) cells and three lumped component resonators realized by the integrated passive device (IPD) technology. The ABCD matrix to S-parameters matrix method is used to calculate the frequency response of the BPF. Moreover, the expressions of transmission zeros (TZs) have been extracted. In the design process, an iterative design approach is proposed to improve the circuit and layout of the hybrid filter based on the packaged acoustic-electric hybrid simulation effect. Finally, two parts of the filter are packaged based on the flip-chip method, and two prototypes for the BPF are measured. The measured results of two chips with 3 dB fractional bandwidth of 13.7% and 15.8% are designed and fabricated, which verifies the validity of the proposed design principle.
期刊介绍:
International Journal of RF and Microwave Computer-Aided Engineering provides a common forum for the dissemination of research and development results in the areas of computer-aided design and engineering of RF, microwave, and millimeter-wave components, circuits, subsystems, and antennas. The journal is intended to be a single source of valuable information for all engineers and technicians, RF/microwave/mm-wave CAD tool vendors, researchers in industry, government and academia, professors and students, and systems engineers involved in RF/microwave/mm-wave technology.
Multidisciplinary in scope, the journal publishes peer-reviewed articles and short papers on topics that include, but are not limited to. . .
-Computer-Aided Modeling
-Computer-Aided Analysis
-Computer-Aided Optimization
-Software and Manufacturing Techniques
-Computer-Aided Measurements
-Measurements Interfaced with CAD Systems
In addition, the scope of the journal includes features such as software reviews, RF/microwave/mm-wave CAD related news, including brief reviews of CAD papers published elsewhere and a "Letters to the Editor" section.
