The method allows reducing the problem to the scalar one-dimensional analysis of the resonator consisting of two Gaussian mirrors, which fit better to a Gaussian mode than spherical mirrors commonly used in that kind of open resonators. The proposed method is validated rigorously in the 20–40 GHz frequency range using a finite difference time domain method.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129123514","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}

These architectures can be implemented in standard Silicon-Germanium technology and are very suitable for highresolution automotive applications that require a high degree of reliability. The bandwidth required for the baseband blocks of the PRN radar systems can be reduced significantly using several methods introduced in this paper. Several single-channel transceivers are cascaded together to build a MIMO radar system with a flexible number of channels. The transceivers are equipped with binary phase-shift keying modulators and I/Q receiver. A large set of suitable pseudo-random binary sequences with different desirable properties is available.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131071645","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}

Zukocinski","doi":"10.23919/MIKON.2018.8405261","DOIUrl":"https://doi.org/10.23919/MIKON.2018.8405261","url":null,"abstract":"The paper presents a set of 3 ultra-wideband bandpass filters for the upper UWB band (5.8 GHz to 10.6 GHz). The filters are development versions of a novel multi-mode stepped-impedance resonator (SIR) planar structure with central via to ground. The new SIR is implemented in microstrip technology. It has a single centrally located via to ground which provides a new mechanism for coupling of the SIR modes. The first filter presented in the paper follows the basic concept of the new SIR whereas the other two filters exploit longitudinal symmetry to bisect the SIR and create half-structures. The second filter uses an in-line cascade of two half-structures while the third filter is a folded cascade of the two half-structures. These examples show basic properties with pros and cons of the new SIR. The cascade of the two half-structures is used to easily increase resultant filter order and performance of frequency characteristics. Folding the cascade can be used to build a new filter structure with some potentially interesting properties. One of the benefits of the presented SIR filters is a direct contact port coupling and no need for more problematic very narrow gaps to couple the structure with the input and output lines. This in turn allows for making the new filters on thin substrates. Another benefit is an extended stop band comparing to the classic SIR.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114249188","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 GaN MMIC LNA has an average noise figure of 1.43 dB over the band and a minimum value of 1.27 dB at 23.2 GHz, which can compete with GaAs and InP MMIC LNA. The small-signal gain is between 22 and 25 dB across the band, the input and output return losses of the MMIC are less than −10 dB. The P1dB and OIP3 are at 17 dBm and 28 dBm level. The four-stage MMIC is 2.3×1.0 mm2 in area and consumes 280 mW DC power.
