  • Low-Cost Surrogate Models for Microwave Filters

    Publication Year: 2016, Page(s):969 - 971
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (378 KB)

    A novel low-cost kriging-based multivariable parametric macromodeling technique for microwave filters is presented. Kriging is used to model both the residues and poles of a microwave filter’s reflection coefficient, and the zeros of the transmission coefficient. The proposed residue-pole-zero (RPZ) technique is demonstrated to efficiently model a high dimensional (8D) microwave filter with... View full abstract»

  • Novel 1.5-1.9 GHz Tunable Single-to-Balanced Bandpass Filter With Constant Bandwidth

    Publication Year: 2016, Page(s):972 - 974

    A novel tunable single-to-balanced bandpass filter is proposed in this letter. It consists of pairs of stepped-impedance resonators (SIRs), which are connected by back-to-back varactors in between. Based on such a simple structure, the filter can cover from 1.5 GHz to 1.9 GHz with constant absolute bandwidth, and exhibit differential outputs in each tuning state. The amplitude and phase imbalances... View full abstract»

  • A Quintuple-mode Wideband Bandpass Filter on Single Metallic Cavity With Perturbation Cylinders

    Publication Year: 2016, Page(s):975 - 977
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (657 KB)

    A quintuple-mode wideband bandpass filter (BPF) on a single circular waveguide cavity with perturbation-oriented cylinders is proposed. These five resonant modes are the fundamental TM01 mode, a pair of TM11 degenerate modes, and a pair of TE11 degenerate modes. Three metallic cylinders are installed on the bottom of an intra-cavity to excite TM modes, and two coax... View full abstract»

  • Compact Hexagonal Shape Elliptical Low Pass Filter With Wide Stop Band

    Publication Year: 2016, Page(s):978 - 980
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1110 KB)

    In this work a new hexagonal shape compact elliptical low pass filter (LPF) is introduced. To improve and extend the stop band, two additional transmission zeros are created by introducing three semi-circular slots in the ground plane. Insertion loss is <0.85dB in the range of 0-1.5 GHz within the pass band and return loss is >18 dB in the entire pass band. Rejection band is extended... View full abstract»

  • Miniaturization of SIW Cavity Filters Through Stub Loading

    Publication Year: 2016, Page(s):981 - 983
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (914 KB)

    This article reports on a simple yet efficient miniaturization technique of substrate integrated waveguide cavity resonators through stub loading. The stubs are attached to the cavity side edges and they are coupled with the magnetic fields of the cavity. This setup allows the stub loaded cavity to operate below its fundamental resonant frequency. This miniaturization technique is demonstrated by ... View full abstract»

  • Filtering Power Divider With Good Isolation Performance and Harmonic Suppression

    Publication Year: 2016, Page(s):984 - 986
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1137 KB)

    A microstrip filtering power divider (FPD) with good isolation performance and harmonic suppression is presented. By replacing a simple resistor with a novel distributed stepped-impedance resonator network, better isolation and wider stopband are simultaneously attained. A transmission-matrix-based analysis method is then extensively described to determine the circuit geometrical parameters at the... View full abstract»

  • Microstrip T-Junction Power Divider With Exponentially Tapered Transmission Lines

    Publication Year: 2016, Page(s):987 - 989
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (776 KB)

    A method is provided for calculating the port parameters of an exponentially tapered power divider. Derived from the general solution for the input impedance of an exponentially tapered line, a design methodology for power dividing ratios from 2–10 dB is shown. An analytic formula for the power dividing ratio is expressed in terms of input impedances of the T-junction. Two devices are fabri... View full abstract»

  • An Asymmetric 2.4 GHz Directional Coupler Using Electrical Balance

    Publication Year: 2016, Page(s):990 - 992
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (870 KB)

    The concept of electrical balance is used to achieve wideband isolation in an asymmetric 2.4 GHz directional coupler. An intuitive approach using impedance transformation property of transmission lines is used to develop the theory for designing arbitrary-coupling-ratio directional couplers. A coupler based on this theory is designed and fabricated on a two-layered RO4003C PCB. The coupler achieve... View full abstract»

  • Compact 6.5-28.5 GHz On-Chip Balun With Enhanced Inband Balance Responses

    Publication Year: 2016, Page(s):993 - 995
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (990 KB)

    In this letter, a miniaturized on-chip stacked-spiral-coupled (SSC) Marchand balun is proposed with wideband operation, i.e., fractional bandwidth (FBW) >125%. To improve the inband balance responses (i.e., amplitude- and phase-balances), the self-coupled compensation line and center-tapped ground-shield with deep trench are introduced. To verify the mechanism of structures mentioned... View full abstract»

    A passive fully inkjet-printed circuit on a plastic based flexible substrate for increasing the communication read range of an NFC based system is proposed. Two parallel coils resonating at 13.56 MHz are used for the improvement of coupling between the transmitter and receiver. The proposed system behaves like a lens by concentrating the absorbed magnetic energy from a wide area in a small focal r... View full abstract»

    Based upon two-tone measurements, 5dB improvement in the linearity behavior of drain extended MOS (DeMOS) device is reported by novel drain engineering. The presented modification significantly improves the device saturation characteristic, ON resistance and transconductance without affecting the breakdown behavior. Formation of IMD sweet-spot by device design is shown and verified using DeMOS dev... View full abstract»

  • A Compact Mixer-First Receiver With >24 dB Self-Interference Cancellation for Full-Duplex Radios

    Publication Year: 2016, Page(s):1005 - 1007
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1197 KB)

    This letter presents a single-channel full-duplex receiver with tunable self-interference (SI) cancelling capability through LO phase shifting. The receiver takes advantage of high linearity of the passive mixer-first architecture to eliminate SI without degrading sensitivity due to inter-modulation distortion. The proposed receiver exhibits a DSB noise figure of 8.6–12.5 dB over an operati... View full abstract»

    This work proposes an improved technique for accurate, contactless measurement of the absolute voltage waveforms of microwave circuits, employing a passive electric-field sensing probe. The proposed technique uses an electromagnetic model of the interaction between the probe and a device under test, to allow the extraction of the coupling capacitance variation versus frequency. Employing these inf... View full abstract»
