| | TUPE-1 | Optically Generated Sub-THz Continuous Wave Using Feedbacked 3rd Order Double Sideband-Suppressed Carriers (DSB-SCs) | 3:00 PM-5:00 PM | S. Kim, S. Kang, M. Kwak, K. Kang, Electronics and Telecommunications Research Institute, Daejeon, Republic of Korea |
(1790) | An optically generated sub-THz continuous wave (CW) using feedbacked 3rd order double sideband suppressed carriers (DSB-SCs) is proposed to realize a source of THz communication systems. In this paper, we have generated 3rd order optical harmonics using a 20 GHz microwave local oscillator. We have increased the 3rd order optical harmonics using our proposed optical feedback scheme. Then, they are photomixed by a photomixer for generating the sub-THz CW signals. Comparing with conventional DSB-SC techniques, the amplitude of the 3’rd order optical harmonics and the photomixed output power have improved about 15 dB and 30 dB, respectively. Consequently, the proposed technique is very useful for generating sub-THz CW signals using low frequency local oscillators. | | |
TUPE-2 | A Broadband Heterostructure Barrier Varactor Tripler Source | 3:00 PM-5:00 PM | T. Bryllert1, J. Vukusic2, A. Olsen1, J. Stake2, 1Wasa Millimeter Wave, Torslanda, Sweden, 2Chalmers University of Technology, Goteborg, Sweden |
(1640) | We present the first demonstration of a broadband Heterostructure Barrier Varactor tripler, designed to cover a major part of the WR-8 waveguide band. The source comprises a waveguide housing, a six-barrier InP-HBV diode flip-chip mounted on an AlN microstrip filter circuit. The conversion loss 3-dB bandwidth was measured to 17 % at a center frequency of 112 GHz. The maximum output power was more than 15 mW for an input power of 300 mW. There are no mechanical tuners or DC-bias, which simplifies assembly and allows for ultra-compact design. | | |
TUPE-3 | Highly Directive Package-Integrated Dipole Arrays for Low-Cost 60-GHz Front End Modules | 3:00 PM-5:00 PM | A. L. Amadjikpè1, D. Choudhury2, G. E. Ponchak3, J. Papapolymerou1, 1Georgia Institute of Technology, Atlanta, United States, 2Intel Corporation, Hillsboro, United States, 3NASA Glenn Research Center, Cleveland, United States |
(1665) | Package-integrated highly directive dipole antenna and dipole array with an original feeding technique are presented. The proposed design features excitation of low-cost organic-based substrate elevated directive dipoles with vias. A miniature substrate embedded feed network is provided for direct via interconnection between the antenna and a chip embedded in the same stack-up. The simulated single dipole (10 × 10 × 0.635 mm3) exhibits more than 11 GHz bandwidth (56 to 67+ GHz), 7.83 dBi peak directivity, and 91.7% efficiency. A prototype of an 8-element dipole array (22 × 11 × 0.635 mm3) is measured and exhibits 8 GHz bandwidth (56.6 to 64.6 GHz), 15.1 dBi peak gain at 61 GHz, and 75 to 83% estimated efficiency. | | |
TUPE-4 | SiP-based 60GHz 4x4 Antenna Array with 90nm CMOS OOK Modulator in LTCC | 3:00 PM-5:00 PM | M. F. Karim1, M. Sun1, M. L. Ong1, Y. Guo2, J. Brinkhoff3, K. Kang3, F. Lin3, 1Institute for Infocomm Research, Singapore, Singapore, 2National University of Singapore, Singapore, Singapore, 3Institute of Microelectronics, Singapore, United States |
(1770) | A 60GHz 4x4 circular polarized (CP) patch array antenna with a 90nm CMOS OOK modulator are designed and integrated in low temperature cofired ceramic (LTCC) substrate to form a SiP-based transmitter. By applying a stripline sequential rotation feeding scheme, the CP array exhibits a wide impedance bandwidth (VSWR 2) and 3dB axial ratio (AR) bandwidth, both over 8GHz. It has a beam-shaped pattern with a 3dB beamwidth of 20º and a peak gain of 16.8dBi. The CMOS modulator includes a 60GHz oscillator and switchable amplifiers to provide the OOK modulation. By applying a bond wire compensation scheme and low-loss transition optimization, the CMOS modulator is successfully integrated into the package with 2mil 500μm long bond wires. The final fabricated prototype measures only 22×13×1.4mm3. The 60GHz SiP transmitter is tested with a commercial receiver and a data rate of 2Gbps is demonstrated. The energy usage at 2Gb/s is only 13.2pJ/bit for the modulator. | | |
TUPE-5 | Analysis of Plasmon Excited by Metal-Isulator-Metal Structure with Insulator Thickness of Hundreds of Nanometers | 3:00 PM-5:00 PM | M. Tamura, H. Kagata, Panasonic Electronic Devices Co., Ltd., Kadoma, Japan |
(1181) | This paper presents the analysis of plasmon excited by Meta-Insulator-Metal (MIM) structure with insulator thickness of hundreds of nanometers. Since the surface plasmons on each metal excited by the electromagnetic waves that enters the MIM structure is coupled to each other, the incident wave is probably absorbed. At that time, the standing wave is generated in the insulator. We explain the principle of the MIM structure by confirming it with an electromagnetic simulator. We also confirm that the surface plasmon resonant wave is changed by the variation of the insulator thickness. Furthermore, the MIM structure's resonant wavelengths are calculated using a multilayer filter approach and shows good agreement with 3D simulation and measurement. | | |
TUPE-6 | Energy Detection and Radiation by Metallic Rings Embedded into a Self-Rolled InGaAs/GaAs Micro-Tube | 3:00 PM-5:00 PM | G. Monti1, R. De Paolis1, L. Tarricone1, M. T. Todaro2, M. De Vittorio2, A. Passaseo2, 1University of Salento, Lecce, Italy, 2Consiglio Nazionale delle Ricerche INFM, Lecce, Italy |
(1513) | This paper presents a novel multilayer micro-ring structure suitable to be used as THz emitter or detector. The realization process exploits the self-rolling properties of a suspended InGaAs/GaAs bi-layer obtained by controlled strain release of a thin film from a substrate. Numerical and preliminary experimental results will be presented and discussed. It is demonstrated that the proposed approach is an optimum candidate for the design of very high-frequency resonators. | | |
TUPE-7 | Experimental Characterization of EC-CPW Transmission Lines and Passive Components for 60-GHz CMOS Radios | 3:00 PM-5:00 PM | I. Haroun2, J. Wight1, C. Plett1, A. Fathy3, 1Calreton University, Ottawa, Canada, 2Communications Research Centre Canada, Nepean, Canada, 3The University of Tennessee, Knoxville, United States |
(1616) | In this work, we propose the use of elevated center coplanar waveguide (EC-CPW) transmission lines in CMOS technology to alleviate the technology limitations of achieving extreme impedances with conventional CPW lines, particularly, high impedances. High impedance lines are required to facilitate the design of matching networks and to reduce the size of the passive components by utilizing capacitively loaded high-impedance lines. This paper presents the measured and simulated performance of these lines and their successful implementation in building a 60 GHz compact 90o coupler. The coupler’s size is 0.102 mm2 and is well suited for use in the design of radio front-ends in 60 GHz high data-rate wireless systems. | | |
