The proposed divider consists of a differential passive transformer-based power splitter and three-stage common source power amplifiers. The measurement results show a 7 dB gain at 38 GHz, and a 3 dB bandwidth from 36 GHz to 46 GHz. The output compression point (OP1dB) and saturated output power are +5 dBm and +6 dBm, respectively. The isolation between input and output ports is better than 30 dB from 10 GHz to 80 GHz.","PeriodicalId":108280,"journal":{"name":"2014 1st Australian Microwave Symposium (AMS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128917661","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}

Phased array radar antenna uses large number of transmit/receive modules spread over the entire physical area of antenna. The received echo signal is processed with the help of various microwave and data signals. This requires distribution of large number of coaxial cables across antenna panel to perform beam forming and other signal processing functions for target detection. An optical distribution network is proposed for transmission of multiplexed microwave signals on single optical fiber on the basis of link power budget calculations. The results have been experimentally tested for S band frequency signals from 50MHz to 4GHz. Analysis is also carried out to observe the effect of extreme temperature on performance of optical components.","PeriodicalId":108280,"journal":{"name":"2014 1st Australian Microwave Symposium (AMS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124524111","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}

One of its main symptoms is the accumulation of fluid (mainly water) inside the lungs. Fluid accumulation changes the dielectric properties of the lungs' tissues. Thus, microwave radar techniques can be utilized to detect those properties changes as an early sign of congestive heart failure. The directivity and operating bandwidth of the employed antenna in microwave techniques are among the important factors that affect the accuracy of the detection. In this paper, we investigate these effects using a fully integrated system designed for the early stage congestive heart failure detection. This system consists of an adjustable platform which holds and displaces the antenna along a torso phantom. The utilized antenna is connected to a custom made microwave transceiver which performs the data acquisition process. A laptop is used to control the operation of the system and process the captured signals.","PeriodicalId":108280,"journal":{"name":"2014 1st Australian Microwave Symposium (AMS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125192623","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}
