The transformer-based inductive coupled resonators at the input of low-noise amplifier provide a wideband signal transformation and impedance matching effectively. Also, several circuit techniques such as GM boosted and 3D-inductors are employed for the LNA and mixer to achieve high circuit performance. The proposed receiver is fabricated using 0.18-μm SiGe BiCMOS technology with a total power consumption of 60 mW. Measured results show that the conversion gain is of 36 dB featuring an excellent gain flatness (±1dB) with the IF bandwidth up to 1.5 GHz, noise figure lower than 8.5 dB, and output P1dB compression point higher than 3 dBm for the IF frequency, respectively.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132514871","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}

By flip-chip bonding a high performance schottky diode onto a separately fabricated passive circuit having a quartz substrate, a quasi-monolithic millimeter-wave integrated circuit (Q-MMIC) mixer is achieved. Compare to MMIC, the discrete device and passive circuitry of the Q-MMIC are fabricated separately, thus the fabrication process is simplified and the cost is reduced. The measurement results show the conversion of the developed mixer is less than 13 dB over the full W-band, as a 46 GHz LO signal with a 10 dBm power is pumped, which means the IF bandwidth can up to 18 GHz. A minimum conversion loss of 8 dB at an RF of 90 GHz and LO of 46 GHz is also observed from the measurements. The total size of the mixer is 2.2 mm× 4.0 mm.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133208512","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}

Since the MAI and beat noise pose a significant impact on system performance in T/W optical CDMA system, using error correction code is an effective way to alleviate such adverse impact. Accordingly, the bit error rate can be further decreased. The coding mechanism we employ is based on trellis coded modulation and equal weight orthogonal signaling scheme, which can drastically improve the throughput of the optical network. In addition to the multiple access interference and beat noise, some negative effects in system performance are also taken into account, which include thermal noise, shot noise, and relative intensity noise.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123991235","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 proposed Luneberg lens is composed of an array of complementary circle cells and embedded in a parallel-plate TEM waveguide.

With the symmetry of the circle cell, the proposed lens can transform cylinderical wave excited by the source at arbitrary location on the surface of the lens to plane wave.

The spotlight beams can be steered electronically both in azimuth and elevation directions to provide mobile cellular services at high-demand “hot-spot” areas where high capacity service is required.

Both the miniaturization of antenna elements and decoupling of antenna arrays have become significant problems to solve. This paper firstly discusses the usage of lossless passive network to decouple strongly coupled antennas, such as some previous works done by other authors. Then this paper mainly concentrates on the Eigen mode decoupling theory and finds that the radiation efficiency is affected by the decoupled network because it changes the Rayleigh quotient of the whole network. Furthermore, this paper uses microstrip branch-line directional coupler to decouple two strongly couples dipoles. It comes out an isolation below -25dB at a center frequency of 3.25GHz. The passive decouple network's effect to the two-element array's radiation efficiency is analyzed in detail. And it turns out to a conclusion that the function of the decoupled network can increase the radiation ability of the whole structure.","PeriodicalId":164534,"journal":{"name":"2015 IEEE International Wireless Symposium (IWS 2015)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124922532","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}
