In this paper, a compact square stub-loaded band pass filter (BPF) is designed and investigated for quality factor improvement analysis. A detailed analysis has been presented to demonstrate the superior power handling capability of the proposed microstrip bandpass filter without any degradation in its electrical performance parameters. For this purpose, square-type stubs are incorporated in the proposed bandpass filter which reduced the maximum peak voltage and increased the high peak threshold, instead of using sharp edges. Also, an in-depth analysis of peak voltage with a center frequency of 2.1 and 4.2 have been carried out by considering some parameters like pressure and quality. The proposed bandpass filter shows minimum peak voltage of 1.61 V and 1.59 V across the frequency of 2.1 GHz and 4.2 GHz which covers the application of mobile and radio altimeters. The designed BPF shows the minimum heat generation of 0.29 and 0.89 per watt at the resonating frequencies of 2.1 and 4.2 GHz. Furthermore, the proposed bandpass filter presents an in-depth analysis of several characteristic parameters such as return loss, insertion loss, power loss, delay in group and phase, current distribution, H and E field distribution and maximum power loaded and unloaded quality factor.

“…Regarding the importance of studying the peak power limits that microwave devices can withstand, some works have focused their efforts on studying the gas breakdown in RWs [35], [36], [37]. Some other contributions have analyzed this same physical effect in planar devices [6], [38] and several design solutions have been proposed to enhance the PPHC [39], [40], [41]. With respect to previous research related to the corona discharge breakdown thresholds in GW technology, a preliminary study based on simulations for guided structures can be found in [42], where measured results are not presented.…”

In-Depth Study of the Corona Discharge Breakdown Thresholds in Groove Gap Waveguides and Enhancement Strategies for Inductive Bandpass Filters

et al. 2022

This work focuses on the study of the corona discharge breakdown in groove gap waveguides (GGWs) and inductive bandpass filters (BPFs) based on this technology. With the main aim of improving the peak power handling capability (PPHC), the location of the maximum normalized electric field strength (| ÊMAX |) as a function of the geometrical parameters is analyzed. First, the research deals with wave-guiding structures, comparing the distribution of the transverse electric TE 10 -like mode of a GGW to that of an equivalent rectangular waveguide (RW). Next, a design strategy based on the adjustment of the geometrical dimensions of the bed of nails is proposed, thus achieving a considerable reduction of | ÊMAX |. The second part of this paper aims for vertically polarized GGW BPFs, where the inductive irises become the most critical part of the component. By a simple modification of their dimensions, a second design criterion is suggested for improving the PPHC. Finally, several Ku-band BPFs centered at 14 GHz and 16 GHz have been manufactured and experimentally verified at the European High-Power Radiofrequency Space Laboratory. This measurement campaign shows peak power thresholds up to 1.09 kW and 3.59 kW at 600 mbar for the non-and full-optimized GGW BPFs, respectively, thereby demonstrating a PPHC enhancement up to 5.16 dB in the high-pressure range when both strategies, proposed in this work, are used.INDEX TERMS Corona breakdown, gas discharge, groove gap waveguides, microwave bandpass filters, peak power handling capability (PPHC), power applications, voltage magnification.

“…The ionisation effect is a serious issue in both ground and satellite communications where moderate to high power signal levels are required. Due to the increasing problem of corona discharge in microwave devices, a big effort has been devoted in the last decade to understand, model and predict the occurrence of discharges for waveguide structures [2]- [4] and planar technology [5]- [7]. Therefore, it is important to determine which are the threshold RF power levels from which the corona effect arises.…”
