Filtering LNA helps in the miniaturization and reduction in noise figure of the transceiver by eliminating an extra band pass filter (BPF) at the output. A CSIR based BPF structure has been used as output matching network. The dual-band bandpass filtering LNA drains 20-mA of current from a 2.8-V supply voltage. Proposed LNA achieves measured voltage gains of 11.6 and 8.9 dB, reflection coefficients of -25 and -12 dB, and noise figures of 3.96 and 2.85 dB at 2.4 and 5.7 GHz, respectively. Measured characteristics of the designed LNA show reasonable gain at widely separated pass bands in 2.4- and 5.7-GHz WLAN bands with ~ 40 dB of stopband attenuation.","PeriodicalId":307742,"journal":{"name":"2015 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128479908","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 antenna is first simulated using Electromagnetic Simulation software (CST Microwave Studio™). Then it is validated with the measurement on fabricated antenna. The conventional quarter wavelength monopole antenna is a narrow band antenna with bandwidth of the order of 5 to 10 percent of its centre frequency for VSWR less than 2.5, while most of the applications in modern communication and Electronic Warfare (EW) system require wideband antennas. In order to increase the bandwidth of monopole antenna, a matching network is incorporated. The matching network is designed and optimized using Genetic Algorithm (GA) which is a global search technique used in computing to find true or approximate solutions to optimization and search problems.

The present work utilizes 130nm SiGe HBT transistors to investigate the performance of low noise amplifier (LNA) for 40GHz and 60GHz wireless personal area networks (WPANs). The transfer gain S2i was found >9dB with 3-dB bandwidth (BW)>5GHz in the bands of interest. Excellent simultaneous matching at input (S11≤-20dB) and output (S22≤-10dB) with noise figure (NF)<;2.5dB at both the bands were obtained. Theoretically, predicted S-parameters of the LNA were found closely matched with corresponding simulated results. The input third-order intercept (IIP3) was found > 3.0dBm in the bands of interest. The graph of performance ratio (R=S21/PDC) versus noise factor F gives significant advantage for SiGe HBT LNA (i.e. achieve high R at low F) as compared to GaAs HBT and Si CMOS technologies. A new figure-of-merit (FoM) involving S2i, noise factor F, IIP3 and power consumption PDC was found to be significantly higher for SiGe LNA than a previously published experimental result for silicon CMOS LNA.","PeriodicalId":307742,"journal":{"name":"2015 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864981","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}
