The radial combiner is comprised of three parts: a center feed, a radial line, and peripheral waveguide ports. The center feed is comprised of two sections: a rectangular waveguide section and a mode transducer section. The latter is a circular waveguide fed by four-way in-phase combiner to convert the rectangular waveguide TE10 mode to a TE10 circular waveguide mode for in-phase feeding of all peripheral ports. For design evaluation, the 12-way combiner was built and tested but also two back-to-back test fixtures, one for the mode transducer and the second for the radial combiner were fabricated and tested as well. The measured insertion loss and phase imbalance of the combiner over a 10% operating bandwidth are less than 0.35 dB and ±5°, respectively. The structure is suitable for high power and should handle few kilowatts.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"27 4 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84013485","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 development of secondary launch systems to provide a reasonably priced ride to space has increased the number of small satellites in orbit. Recent subsystem developments have also supported this revolution. One area that has been slow to develop is high rate communications. Early CubeSat systems were built on the amateur satellite service, but the available data rates are low. Efforts are evolving to develop high rate CubeSat transceivers. This paper will provide an overview of current CubeSat communication systems capabilities in addition to details about an effort to develop a high rate CubeSat communication system that is compatible with the NASA Near Earth Network. The system includes a 200kbps S-Band receiver and a 12.5Mbps X-Band transmitter.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"153 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77998598","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}

Optical tachymeters are well established but they have shortcomings under harsh environmental conditions such as dense smoke, fog, dust, rain or snow. As a robust alternative, we developed an innovative radar tachymeter for precise and highly reliable operation. This device is a 24 GHz single-input and multiple-output radar system with a frequency-modulated continuous-wave secondary radar base station that measures the distance to a cooperative responder unit. The synthesizer is optimized for low phase noise and features highly linear frequency modulation for high-precision ranging. The radar system incorporates a sparse antenna array with 1 transmit and 8 receive channels. Angle and range are precisely estimated with a spatial optimal filter algorithm and a dedicated synchronization concept implemented on a compact embedded platform. The developed radar tachymeter has been tested in indoor scenarios as well as on a truck-mounted crane. The measurement campaigns showed that the root-mean square errors are as low as 0.1° and 1 cm, for angle and range respectively.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"25 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72806694","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}

Despite a strong interest of industries in this technology, key issues like miniaturization and security of WSN nodes has not been solved yet. State-of-the-art WSN nodes do not provide credible security nor satisfying configurability and miniaturized implementations. This publication deals with these limitations and presents a WSN node that provides security, configurability, and a miniaturized design. To show the sensor node feasibility, the WSN node is implemented within a smart home demonstrator. Additionally, a miniaturized pre-study WSN node design is presented using the novel embedded wafer level ball grid array (eWLB) packaging technology. Furthermore, an eWLB based WSN node design is proposed that further miniaturize the presented WSN node.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"221 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79885815","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 novel topology comprises two auxiliary inductors paralleled in the balanced input and output of the conventional lattice topology. The performance of the filter is evaluated theoretically as well as experimentally. It is found that, in multistage configuration, the number of auxiliary inductors decreases exponentially, enabling the compact integration of filter chips. This topology is further validated from the experiment, with the filter bandwidth measured to be 400 MHz at central frequency of 3.25 GHz (12.3 % relative bandwidth), which is in excellent agreement with the simulation.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78641430","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 approach eliminates the need for multiple costly IQ modulators and baseband signal component separation found in conventional outphasing power amplifier systems, which have previously required both an RF carrier input and a separate baseband input to synthesize a modulated RF output. A novel RF signal decomposition network enables direct RF-input / RF-output outphasing by directly synthesizing the phase- and amplitude-modulated RF signals that drive the branch PAs from the modulated RF input waveform. The technique is demonstrated at 2.14 GHz in a four-way lossless outphasing amplifier system with transmission-line-based power combiner. The resulting proof-of-concept outphasing power amplifier has a peak CW output power of 95 W, and peak drain efficiency of 72%.","PeriodicalId":6493,"journal":{"name":"2015 IEEE MTT-S International Microwave Symposium","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76333223","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}

Among these oscillating elements, 16 are used for radiation source cores and 4 are used for synchronization bridges.
