Although software programming makes things reconfigurable, the limitation of hardware components cannot be avoided. These limitations translate to the problem of DC offset, local oscillator (LO) leakage and in-phase/quadrature-phase imbalance along with bandwidth limitation. This paper presents a digital intermediate-frequency-based method to expand the bandwidth of the multichannel SDR transmitter using a single LO configuration while avoiding RF imperfections. The proposed method is experimentally validated.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126046453","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}

A 28 GHz mmW module has been designed, which integrates MMICs (PA, LAN, converter, amplifier), and passives, including LD combline filter, parallel coupled line (PCL) BPF, patch antenna array with embedded splitter and matching network, and bias network, onto a single substrate. Here the IC mounting cavities are formed from trench-vias and with precise dimensional control. The multilayer miniaturized components, using lumped-distributed (LD), broadside coupling, and meander-line approaches, have been designed and characterized off-chip, covering 2 GHz to 100 GHz. These include LD combline filter, PCL BPF, couple, EM coupled patch antenna array, and embedded splitter and matching network. A new multilayer coplanar waveguide capacitor configuration, where for increasing the capacitance density yet maintaining high performance, a number of pairs of parallel plates were employed horizontally. Using this configuration, a range of off-chip capacitors are designed and modelled, with a self-resonance frequency beyond 40 GHz. Further TFMS and FGCPW interconnect were designed and accurately characterized to 100 GHz for various transverse dimensions with a low loss for mmW MCM applications.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121854600","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}

Coaxial monopole wire antennas provide minimum invasiveness, but the current induced on the outer conductor radiates backwards and extends the heating zone beyond the antenna active zone. Coaxial BALUN is widely used for choking the back current at the cost of increased applicator size and invasiveness in the tissue. In this paper, we investigate the scope of resistive coating on the outer conductor of a 915 MHz monopole antenna proposed for hyperthermia treatment. Numerical simulations are presented for a conventional coaxial monopole with and without a thin coating of PEDOT:PSS to study the influence of the resistive coating on suppressing the current induced on the outer conductor and tissue specific absorption rate (SAR) for varying antenna insertion depth in the tissue.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134176529","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 confinement and the propagation of terahertz (THz) signal can easily be controlled by tuning the geometrical parameters of the grooved T-shaped SSP cells. The asymptotic frequency of the grooved T-shaped SSP unit cell basically restrict the THz signal propagation beyond this point and hence, it might act as a high cutoff frequency point for the designed waveguide, which can be used for low pass filter applications. The proposed idea of coplanar plasmonic waveguide is experimentally validated in microwave frequency region by scaling up the geometries of the proposed corrugated CTPW line, which are in good agreement with its simulated counterpart.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126724574","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}
