The groove gap waveguide technology has proven to be suitable for the realization of passive components up to high frequencies. However, the overall structure including pin width and pin distance becomes smaller for higher frequencies, which increases manufacturing difficulties. Especially the pin distance defines the manufacturing costs and effort with respect to the computerized numerical control (CNC) milling approach, which is often used for fabrication. The interdigital-pin groove gap waveguide approach is therefore applied, increasing the maximal allowed cutter diameter compared to standard groove gap waveguide technique. The design and realization of a third order W-band (75GHz-110GHz) groove gap waveguide filter is discussed and potential approaches for further reducing the manufacturing effort are proposed.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"37 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116772800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, specific Monolithic Microwave Integrated Circuits (MMICs) Power Amplifiers (PAs) were developed on a commercially available 100 nm gate length GaN on Silicon (GaN-Si) process (OMMIC process D01GH). The design was carried out considering space reliability constraints on electrical parameters and accounting for the spacecraft temperature limits, which are extremely challenging for this technology, to keep the junction temperature of all devices below $160^{circ}mathrm{C}$ in the worst-case condition (i.e., maximum environmental temperature of $85^{circ}mathrm{C})$. The final MMIC, based on a three-stage architecture, demonstrates on wafer and in pulsed condition to achieve a minimum output power and power added efficiency (PAE) of 10W (40dBm) and 35% (with a peak of 45%) in the full Ka-band satellite downlink, i.e., from 17.3 GHz to 20.2 GHz. The packaged version demonstrates in continuous wave (CW) conditions an output power larger than 39.5dBm with a PAE better than 30%. Moreover, long-term (24h) CW test at saturated output power has shown almost negligible performance degradation, thus providing confidence in the robustness of the selected GaN-Si technology.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122309621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we present a study on the effect of feedback interferometry which manifests itself in devices implemented in a 130 nm SiGe BiCMOS integrated-circuit technology. The emitters are based on a voltage-controlled oscillator (VCO) that employs a differential Colpitts configuration with optimized emission frequency at fundamental harmonic. The radiation is outcoupled through the substrate side using a hyper-hemispheric silicon lens. The source emits up to 0.3 mW of propagating power, which is tuneable in the frequency range from 258 to 262 GHz. When the part of radiation gets reflected from an arbitrary object located in the beam path and couples back into the oscillator, it interferes and produces a self-mixing current which in magnitude can exceed several percent compared with the bias current. Produced current change can be measured either in the dc regime or by employing signal modulation techniques. Furthermore, the magnitude of self-mixing strongly depends on the selected bias conditions. Finally, we demonstrate the applicability of the self-mixing effect to perform coherent reflection-type imaging.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127845688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presented procedure makes use of an arbitrary number of unknown target’s positions and is suitable for nearfield application.

The procedure was tested utilizing a six-port-based continuous-wave radar operating at 2.35 GHz for various number of target’s positions and their spread, showing the obtainable distance measurement error not exceeding 0.012 of the wavelength. Furthermore, the obtained measurement error distribution allows for defining simple and practical guidelines for calibrating radars with the use of the proposed method.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132513622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
