  • 89 GHz zero-bias Schottky detector for direct detection radiometry in European satellite programme MetOp-SG 
    HOEFLE, M.; PENIRSCHKE, A.; COJOCARI, O.; DECOOPMAN, T.; TRIER, M.; PIIRONEN, P.; PÉRICHAUD, M. G.; JAKOBY, R. (The Institution of Engineering and Technology, 2014)
    An 89 GHz waveguide coupled direct detector based on a low-barrier Schottky diode is presented. The main focus is to reduce white and 1/f noise to achieve high signal-to-noise ratio values above 35 dB. The design also ...
  • Broadband zero-bias Schottky detector for E-field measurements up to 100 GHz and beyond 
    HOEFLE, M.; PENIRSCHKE, A.; COJOCARI, O.; JAKOBY, R. (IEEE, 2013)
    A broadband detector for electrical field measurements is presented in this paper, deploying an attenuated dipole resonance. High sensitive zero-bias Schottky diodes with anode diameters of 1.5μm allow electrical field ...
  • Compact quasi-optical Schottky detector with fast voltage response 
    PENIRSCHKE, A.; SOBORNYTSKYY, M.; PREU, S.; MITTENDORFF, M.; WINNERL, S.; HOEFLE, M.; COJOCARI, O.; JAKOBY, R. (IEEE, 2014)
    Zero-bias Schottky diode detectors operated at room-temperature are the choice for applications, where the ultimate sensitivity of a cryogenic detector is not needed. Furthermore Schottky detectors are intrinsically much ...
  • European Schottky-Diode Based Receiver Technology 
    COJOCARI, O.; HOEFLE, M.; MORO-MELGAR, D.; OPREA, I.; RICKES, M. (IEEE, 2019)
    This contribution summarizes recent achievements of European MM- and SubMM-Wave receiver technology using Schottky diodes and THz-MICs fabricated by so-called Film-Diode (FD) process. The FD-process has particularly been ...
  • High power 150 GHz Schottky based varactor doubler 
    MONTERO-DE-PAZ, J.; SOBORNYTSKYY, M.; HOEFLE, M.; COJOCARI, O. (IEEE, 2016)
    Presented is the design, simulation and characterization of a high power 150 GHz Schottky based varactor doubler. The designed doubler works in the 67.5 GHz-82 GHz input frequency band with an input power of 25 dBm (315 ...
  • Highly responsive planar millimeter wave zero-bias Schottky detector with impedance matched folded dipole antenna 
    HOEFLE, M.; HAEHNSEN, K.; OPREA, I.; COJOCARI, O.; PENIRSCHKE, A.; JAKOBY, R. (IEEE, 2013)
    A compact highly responsive planar zero-bias Schottky detector is proposed for uni-planar and low-cost fabrication. Various zero-bias Schottky diodes are investigated, in particular the optimization of impedance matching ...
