  • Modeling and design aspects of millimeter-wave Schottky varactor frequency multipliers

    Design and optimization of frequency multipliers for millimeter and submillimeter wavelengths have been previously performed using harmonic- balance techniques together with equivalent circuit models. Using this approach it is difficult to simultaneously design and optimize the diode device and the multiplier circuit. This work demonstrates results from numerical semiconductor simulation coupled with the harmonic-balance technique. The good agreement between the calculated and published experimental data for the output power and efficiency is essentially due to the incorporation of impact ionization in the numerical model. Details on the device behavior and circuit operation at different power levels are provided.

  • Parametric modeling of folded waveguide circuits for millimeter-wave traveling wave tubes

    Summary form only given. Results of different models are compared for calculating effective phase velocities and interaction impedances of folded waveguide slow wave circuits for use in millimeterwave and submillimeter-wave traveling wave tubes. These parameters are needed for 1D parametric model simulations of folded waveguide traveling wave tubes (FWTWTs). The models investigated include approximate analytic expressions, equivalent circuits, three-dimensional (3D) finite difference models, and 3D finite element models. The phase velocity predictions are compared with experimental measurements of dispersion in a 40-55 GHz folded waveguide circuit. The various model results are incorporated into the CHRISTINE1D code to obtain predictions of small signal gain and saturated power in a 40-55 GHz, 100 W FWTWT. The comparisons of CHRISTINE1D simulations and measured frequency-dependent gain provide a sensitive, confirming assessment of the accuracy of the simulation tools.

  • Modeling and design aspects of millimeter-wave and submillimeter-wave Schottky diode varactor frequency multipliers

    Design and optimization of Schottky varactor diode frequency multipliers for millimeter and submillimeter wavelengths are generally performed using harmonic balance techniques together with equivalent-circuit models. Using this approach, it is difficult to design and optimize the device and multiplier circuit simultaneously. The work presented in this paper avoids the need of equivalent circuits by integrating a numerical simulator for Schottky diodes into a circuit simulator. The good agreement between the calculated and published experimental data for the output power and conversion efficiency originates from the accurate physical model. The limiting effects of multiplier performance such as breakdown, forward conduction, or saturation velocity are discussed in view of the optimum circuit conditions for multiplier operation including bias point, input power, and loads at different harmonics. It is shown that the onset of forward or reverse current flow is responsible for the limitation in the conversion efficiency.

  • Schottky-Barrier Diodes for Submillimeter Heterodyne Detection

    The fabrication and packaging techniques which were used to produce high- reliability mixer diodes for millimeter-wave satellite communications systems have been extended to produce Schottky-barrier mixer diodes for use in the submillimeter-wave region from 1 to 0.1 mm. The influence of material and circuit parameters on the performance of Schottky-barrier diodes as heterodyne detectors in the submillimeter-wave region has been considered. The semiconductor material parameters have been optimized and new packaging concepts have been investigated. A new diode package has been developed which incorporates both an integral stripline filter on 0.05-mm-thick quartz and a section of overmoded waveguide. The new package has the advantage of being replaceable in the mixer circuits, and yet it can provide a low-loss interface between the diode package and the mixer circuit. A new surface-oriented device has been developed in which the contact to the Schottky barrier is formed by photolithographic techniques onto the same surface as the ohmic contact. The surface-oriented devices exhibited heterodyne detection into the submillimeter region.

  • A submillimeter-wave planar diode mixer-design and evaluation

    A 345-GHz mixer using a planar GaAs Schottky diode has been designed and tested. The design process used nonlinear and linear numerical mixer analysis as well as scale-model impedance measurements. Using a planar diode eliminates the disadvantages of mechanical instability and labor-intensive assembly associated with conventional whisker-contacted diodes. Test results indicate performance on the same level as that of the best whisker-contacted room- temperature mixers for submillimeter wavelengths.<<ETX>>

  • 9.4: MEMS fabrication of 0.22 THz sheet beam TWT circuit

    0.22 THz sheet beam traveling wave tube amplifier (TWTA) circuits fabricated by microelectro mechanical system (MEMS) processes are under investigation for submillimeter wave applications. Currently, we are investigating three different methods; KMPR UV-LIGA and nano CNC machining. Eigenmode transient simulations show that, accounting for realistic values of our currently achievable fabrication tolerances, the transmission, and dispersion properties of the operation modes of a TE-mode, staggered, double grating circuit are maintained within less than 1 dB and 2% deviation, respectively. Scanning electron microscopy and atomic force microscopy analyses of the fabricated circuit samples demonstrate that both of the MEMS fabrication approaches produce circuits with ± 3 - 5 μm dimensional tolerance and ~ 30 nm surface roughness. Currently, the fabricated circuits are being cold-tested and process conditions will be re-adjusted with respect to a test result for optimization.

  • Phase-shifted double vane circuit (Barnett-Shin TWT) for ultra-wideband millimeter and submillimeter wave generation

    A novel slow wave vacuum electron device circuit, the so-called ldquoBarnett- Shin traveling wave tube (TWT) circuitrdquo, which consists of a half-period- staggered double vane array and a high aspect ratio sheet beam, has been conceived for high power millimeter and submillimeter wave amplification/ oscillation applications requiring extremely wide bandwidth as well as compact size and light weight. Particle-in-cell simulations based on a finite- difference-time-domain algorithm have shown that this circuit has a very wide intrinsic bandwidth (in excess of 50 GHz around the operating frequency of 220 GHz) with a moderate gain of 13 dB. Also, the saturated electronic conversion efficiency is 3 ~ 5.5%, which corresponds to radiation power of 150 ~ 275 W, assuming a beam power of 5 kW. Of particular importance, this structure is based on TE-fundamental mode interaction, which can avoid complex overmoding instability usually causing spurious signal oscillations in the conventional high aspect ratio structure. Moreover, this planar circuit has a simple two- dimensional geometry so as to be thermally and mechanically robust as well as compatible with conventional micro-fabrication techniques. This concept will open promising opportunities in potential applications of versatile electronic devices to the millimeter and submillimeter wave region.

  • Mass produced copper-on-polymer-membrane boards for micromachined millimeter-wave circuits

    Membrane-supported circuits (also known as dielectric-less circuits) have been well known for their negligible dielectric losses and for their allowance of relaxed dimensional tolerances in high-frequency circuit design. However, thus far, most of the commonly known silicon-based membrane-processing technologies require intensive and time-consuming thermal processing. This paper reports a simple but economical processing technique for production of self-supporting polymer-membrane-based printed circuits. Based on a pre-processed copper-on- polymer-membrane board, a planar millimeter/submillimeter wave component can be rapidly prototyped on a 5 /spl mu/m thick polymer membrane with conventional photolithographical processing equipment. The simplicity of the process makes this technology particularly suitable for mass production of millimeter wave or sub-millimeter wave components. Vector-network-analyzer measurement reveals that the transmission losses of general E-plane components are typically less than 0.5 dB/cm across W-band.

  • Planar noncontacting short circuits for millimeter-wave and submillimeter-wave applications

    Adjustable planar noncontacting short circuits for both rectangular and circular waveguides have been designed and tested. The planar configuration allows these short circuits to be fabricated photolithographically, therefore reducing fabrication cost and eliminating the machining tolerance requirements of conventional noncontacting short circuits. Scale model tests show that the new short circuits can offer a return loss <0.1 dB and linear phase variation over a single mode bandwidth. Successful application of a planar short circuit in a 300-365-GHz mixer further demonstrates the usefulness of these short circuits at high frequency.<<ETX>>
