Примечания : Cited References: 10. - This study was carried out under agreement No. 470 dated August 30, 2022, between the Kirensky Institute of Physics (Siberian Branch, Russian Academy of Sciences), the Regional Science Foundation, and ”AO ”NPP ”Radiosvyaz“ as part of a competitive tender of research-andengineering and innovative projects for the first climatological research and education center ”Yenisey Siberia“
Аннотация: The design of a 10th-order waveguide bandpass filter with an additional inductive cross-coupling between non-adjacent resonators has been proposed and studied. An inductive coupling is formed by a U-shaped conductor structure with grounded ends that is formed in the filter cover. This method of cross-coupling organization ensures not only the temperature stability of the characteristics, but also the manufacturability of the structure. The high selectivity of the device is achieved by both the attenuation poles located near the passband, as well as the level of suppression in the stopbands, exceeding 120 dB. The passband loss of the fabricated filter is ~ 0.8 dB at its central frequency f0=18.2 GHz and relative bandwidth Δf/f0=1.5%. The small dimensions (135 x 30 x 10 mm) and the weight of about 200 g of the device, with simultaneously high electrical characteristics show the promise of its use, for example, in on-board and ground-based space communication systems.

Аннотация: New resonator design employing a hairpin stripline conductor with a stub situated on one side of a dielectric substrate and regular stripline conductors (connected to a screen) on the other side. Eigenfrequencies of the first three oscillation modes of this resonator can be made closer to each other, so that the resonances of two modes are involved in the formation of the passband while the third mode resonance forms a minimum of the transmission coefficient adjacent to the passband. A structure comprising four resonators of this type has the characteristic of an eighth-order bandpass filter arranged in a case with 45 × 16 × 6.25-mm internal dimensions possessing f0 = 0.52 GHz central frequency with a 14% relative bandwidth. The filter is highly selective due to the attenuation poles being close to the pass band and a wide high-frequency stopband extending above a fivefold f0 value at a level of –100 dB.

Аннотация: A new miniature design of a highly selective lowpass filter based on a suspended substrate with a two-sided stripline pattern has been developed. The filter frequency response slope (cutoff attenuation rate) and stopband attenuation depth are determined by transmission zeros, the number of which is equal to the filter order. An experimental prototype of a fifth-order lowpass filter on 0.5-mm-thick alumina substrate with dielectric permittivity ε = 9.8 has been synthesized with the aid of numerical electrodynamic analysis of a three-dimensional model. The cutoff frequency of the filter passband at a –1-dB level is fc = 1.75 GHz. The stopband width at a –100-dB attenuation level reaches 4.4fc.

Аннотация: A new monolithic design of a miniature bandpass filter for manufacture by means of multilayer printed-circuit-board technology has been developed. It is demonstrated using a fourth-order filter that multi-conductor strip resonators used in the design ensure both miniaturization and high selectivity of the device. The passband center frequency of the manufactured filter is f0 = 546 MHz, the fractional bandwidth is Δf/f0 = 25%, and the insertion loss is 0.8 dB. The filter has a wide high-frequency stopband, which extends up to a frequency of 10f0 at a level of –30 dB. The filter dimensions are 15.0 × 12.0 × 4.3 mm (0.027λ0 × 0.021λ0 × 0.007λ0, where λ0 is the wavelength in vacuum at frequency f0) and the mass is only 1.8 g. The performances of the filter and the accessibility of its design for surface mounting show that the device has great potential.

FEATURES
Аннотация: A microstrip bandpass filter of new design based on original resonators with an interdigital structure of conductors has been studied. The proposed filters of third to sixth order are distinguished for their high frequency-selective properties and much smaller size than analogs. It is established that a broad stop band, extending up to a sixfold central bandpass frequency, is determined by low unloaded Q of higher resonance mode and weak coupling of resonators in the pass band. It is shown for the first time that, as the spacing of interdigital stripe conductors decreases, the Q of higher resonance mode monotonically drops, while the Q value for the first operating mode remains high. A prototype fourth-order filter with a central frequency of 0.9 GHz manufactured on a ceramic substrate with dielectric permittivity ɛ = 80 has microstrip topology dimensions of 9.5 × 4.6 × 1 mm3. The electrodynamic 3D model simulations of the filter characteristics agree well with the results of measurements.

Аннотация: It is shown that for an optimal substrate thickness ALD technology will be promising for IF bandpass filter designing. A two-conductor stripline ALD resonator with central frequency 200 MHz will have Q-factor 53 with total length 3.7 mm (0.0025λg) and the frequency separation of the first and the second oscillation modes up to 59. Two bandpass filters for VHF and UHF designed and fabricated for commercial application display good agreement between the simulation and the experiment. A 3-pole bandpass filter with central frequency 255 MHz and lateral size 15.8×3.2 mm2 has stopband width 13.5f0 , and a 6-pole bandpass filter with central frequency 1250 MHz and lateral size 4.4×5.1 mm2 has stopband width 9.4f0.

Аннотация: An ultra-wideband bandpass filter formed by cascading of a novel high-pass filter (HPF) and a low-pass filter (LPF) on suspended substrates with a two-sided pattern of strip conductor has been investigated. The high selectivity of the HPF is ensured by the transmission zeros near the passband, the number of which is equal to the filter order. A second-order HPF has been designed on a 0.5-mm-thick substrate with a permittivity of ε = 9.8 using the numerical electrodynamic analysis of a 3D model of the filter. The experimental HPF prototype has a cutoff frequency of fb = 0.25 GHz at a level of –3 dB and a passband that extends to 5 GHz. The ultra-wideband bandpass filter formed by cascading of the LPF and the designed HPF has a fractional bandwidth of Δf/f0 = 150% with a central frequency of f0 = 1 GHz. It has the broad and deep high-frequency stopband, which extends to a frequency of 7.8f0 at a suppression level of –100 dB.

Заглавие : Bandpass filter with an ultra wide stopband designed on miniaturized coaxial resonators
Место публикации : J. Commun. Technol. Electron.: Pleiades Publishing, 2013. - Vol. 58, No. 2. - P.110-117. - DOI 10.1134/S1064226913020022
Аннотация: Characteristics of a new miniaturized coaxial resonator are theoretically investigated. It is shown that the first resonant frequency of the resonator can be significantly lowered relative to the second one and the resonator dimensions can be considerably decreased as compared to those of a traditional dielectric filled quarter wavelength coaxial resonator. Based on the investigated resonator, a fourth order bandpass filter has been designed and fabricated. The filter stopband at a level of no worse than –90 dB extends to the frequency that exceeds the passband center frequency by a factor of 47. Calculated frequency responses are in good agreement with those measured on the fabricated filter prototypes.

Аннотация: A new design of a self-packaged all-PCB ultrawideband filter based on the cascade connection of high-pass and low-pass filters is presented. The novel low-pass and high-pass quasi-lumped filter structure differs from the known one by the existence of cross-coupling between elements producing transmission zeroes at the desired frequency. The filter fabricated using materials with a rather low quality factor has demonstrated a good performance: the central frequency is 0.99 GHz, the 1 dB bandwidth is 151%, the minimum in-band loss is 0.3 dB, the selectivity (Δf 30dB /Δ f 3dB ) is 1.21, and the 40 dB stopband width is 6.10 f 0 .

Аннотация: A new design of a self-packaged all-PCB wideband filter based on the cascade connection of high-pass and low-pass filters is presented. The novel low-pass and high-pass quasi-lumped filter structure differs from the known ones by the existence of cross-coupling between elements producing transmission zeroes at the desired frequency. It is shown that high order structures make it possible to design a wideband filter having the number of transmission zeros in the low-frequency stopband equal to the order of the applied high-pass filter and the number of transmission zeros in the high-frequency stopband equal to half the order of the low-pass filter. An implementation of two-layer metallization of the capacitor plates made it possible to manufacture all three types of filters using the common technology of multilayer printed circuit boards with a good coincidence of the characteristics of the model and the fabricated filters. The filter fabricated using materials with a rather low-quality factor (F4BM/RO4450B/RO4003C) has demonstrated a good performance: the central frequency is 0.99 GHz, the 1 dB fractional bandwidth is 152%, the minimum in-band loss is 0.3 dB, the selectivity (Δf30dB/Δf3dB) is 1.21, and the 40-dB stopband width is 6.16f0.
