Ultranarrow bandpass hybrid filter with wide rejection band.
The theoretical study and the experimental realization of an ultranarrow bandpass filter, joining a fiber Bragg grating and a dielectric mirror directly deposited at the extremity of the fiber tip, is presented. The features of such a filter are in very good accordance with the results of theoretical simulations.
متن کاملUltra-Wideband Bandpass Filter Using Hybrid Microstrip-Defected-Ground Structure
A novel ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about % 110 is presented using the hybrid microstrip-defected-ground structure (DGS). The proposed filter was designed using a combination of hybrid microstrip-defected-ground structure lowpass filter (LPF) with typical quarter-wavelength short-circuited stubs highpass filter (HPF), followed by an optimizati...

Narrow bandpass filters (NBPF) are an important type of thin film filter technology that have become commonplace within the electrooptics industry. These devices are indispensable in fields such as analytical instrumentation, microscopy and telecommunications. NBPF are typically characterized as having high transmission with steep roll-offs and broad isolation. Thin film coating designs that me...
متن کاملAn Adaptive Self-adjusting Bandwidth Bandpass Filter without IIR Bias
In this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. This adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. In addition, an important feature of the proposed structure is that the conventional bias existing ...
متن کاملHigh Selectivity Balanced Bandpass Filter with Tunable Bandwidth Using Stub-Loaded Resonator
A new balanced bandpass filter (BPF) with tunable bandwidth using tri-mode stubloaded resonators is proposed. To tune the differential-mode bandwidth, the two even-mode resonance frequencies and two transmission zeros (TZs) are tuned while the odd-mode resonance frequency keeps unchanged. To realize high selectivity for differential mode, another two TZs are created by the source-load coupling ...
