  • 1/f-noise prediction in millimeter wave detectors based on quasi vertical Schottky diodes 
    HOEFLE, Matthias; PENIRSCHKE, Andreas; COJOCARI, Oleg; AMRHEIN, Andreas; DECOOPMAN, Thibaut; PIIRONEN, Petri; JAKOBY, Rolf (IEEE, 2013)
    A modeling concept for accurate prediction of 1/f-noise in millimeter wave Schottky detectors is presented. The concept is based on DC bias current measurements with precise knowledge of the diode structure. Key aspect is ...
  • Addressing the temperature stability in an 89 GHz Schottky detector design for radiometry 
    HOEFLE, Matthias; PENIRSCHKE, Andreas; AMRHEIN, Andreas; COJOCARI, Oleg; TRIER, Marc; JAKOBY, Rolf (IEEE, 2012)
    A detector design for the 89 GHz channel of direct detection radiometers is proposed with high sensitive zerobias Schottky diodes. Particularly addressed is the diode's RF voltage responsivity drift with temperature at ...
  • Compact and Sensitive Millimetre Wave Detectors Based on Low Barrier Schottky Diodes on Impedance Matched Planar Antennas 
    HOEFLE, Matthias; HAEHNSEN, Katharina; OPREA, Ion; COJOCARI, Oleg; PENIRSCHKE, Andreas; JAKOBY, Rolf (Springer Nature Switzerland, 2014)
    Compact and highly responsive millimeter wave planar Schottky detectors are proposed for uni-planar and low-cost fabrication. For optimum power transfer, the zero-bias Schottky diodes are impedance matched by the antenna ...
  • Compact Schottky barrier diode receiver for E-Band (60–90 GHz) wireless communications 
    MONTERO-DE-PAZ, Javier; HOEFLE, Matthias; OPREA, Ion; COJOCARI, Oleg; GARCÍA-MUÑOZ, Luis Enrique; SEGOVIA-VARGAS, Daniel; JAKOBY, Rolf; CARPINTERO, Guillermo (IEEE, 2012)
    A compact E-Band receiver based on a zero bias Schottky barrier diode, folded dipole antenna and hyperhemispherical silicon lens for wireless communications is presented. Zero bias Schottky diodes were designed and ...
  • Low noise 89 GHz detector module for MetOp-SG 
    HOEFLE, Matthias; COJOCARI, Oleg; SOBORNYTSKYY, Mykola; JANKOWSKI, Andrzej; OPREA, Ion; PENIRSCHKE, Andreas; JAKOBY, Rolf; DECOOPMAN, Thibaut; PERICHAUD, Marie-Genevieve; PIIRONEN, Petri (IEEE, 2015)
    Presented is an 89 GHz waveguide coupled direct detector based on low-barrier Schottky diodes. The design aims for signal-to-noise ratio (SNR) values above 35 dB within 6 dB input power dynamic, with significant white and ...
