Microwave photonic filters (MPFs) with the capabilities of bandwidth reconfigurability and frequency tunability in GHz range are great interest high-speed communications systems. In this paper, we propose a new reconfigurable multiband microwave filter (MPF) using tunable Fabry–Perot Filter (FPF). It is demonstrated by numerical simulations that modification intermodal separation (δλ) multimode...

Microwave photonic filters with arbitrary phase response can be achieved by merging high-repetition-rate electro-optic frequency comb technology with line-by-line pulse shaping. When arranged in an interferometric configuration, the filter features a number of programmable complex-coefficient taps equal to the number of available comb lines. In this work, we use an ultrabroadband comb generator...

The measurement fidelity of superconducting transmon and Xmon qubits is partially limited by the qubit energy relaxation through the resonator into the transmission line, which is also known as the Purcell effect. One way to suppress this energy relaxation is to employ a filter which impedes microwave propagation at the qubit frequency. We present semiclassical and quantum analyses for the band...

A quadband filter for 1.57 GHz GPS, 5.2 GHz WLAN and 3.5 GHz Worldwide Interoperability Microwave Access is designed and tested in this work. A compact Defected Ground Structure (DGS) quad-band microstrip Band Pass Filter, stub loaded Low Pass Filter, short circuited uniform impedance resonator and ring resonator are used to maintain the size and performance. Use of stub resonator at central po...

This paper aims to discuss the filter structures which constitutes a planar inductor, capacitors using microstrip lines and make it tunable taking the advantage of LTCC multilayer design. Investigations of passive multilayer filter structure using low-temperature co-fired ceramic (LTCC) for microwave and radio frequency application is studied. A roadmap for performance and process parameters to...

Abstract—In this paper, the performance of spectrum sliced photonic microwave filter for Radio Over Fiber link is characterized. The proposed filter utilizes parallel Fabry-Pérot filters for spectrum slicing of a broadband source. The filter performance is characterized by measuring the overall Free Spectral Range, 3db Bandwidth, Quality factor and Main Lobe to Sidelobe Suppression level for di...

This paper presents the Waveguide Filter Design (WFD) program using principle of electromagnetic wave theory and Wave Iterative Method (WIM) based on propagation of incident, reflected and transmitted waves in the waveguide for microwave engineering education. After the surveying by questionnaire about the nature in the microwave engineering course, the instructors found that the microwave engi...

* The authors are with the IMTEL Institute, Belgrade, Serbia and Montenegro Abstract – This paper presents a new concept of band-pass filters with capacitive coupled resonators applied for realization of a printed filter in L band. The significant size reduction achieved by the original construction allows filter realization at these very low microwave frequencies. The agreement between the pre...

A novel microwave transversal-filter for Fibre-Optic CDMA (FO-CDMA) is described. The proposed distributed transversal-filter permits the development of receivers for high-speed networks. The transversal filter is aimed to receive efficiently spread signals at speeds of tens of Gchip/s. In order to demonstrate the concept a transversal filter was designed to operate at 10 Gchip/s and programmed...
