  • 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 Discrete Schottky Diodes Based 275-305 GHz Transceiver for FMCW-Rada 
    MORO-MELGAR, D.; COJOCARI, O.; OPREA, I.; HOEFLE, H.; RICKES, M. (IEEE, 2018)
    A heterodyne 275-305 GHz transceiver intended for frequency modulated continuous wave radar applications is presented here. A commercial E-band active multiplication chain is used to provide the required power and frequency ...
  • High Power High Efficiency 270-320 GHz Source Based on Discrete Schottky Diodes 
    MORO-MELGAR, D.; COJOCARI, O.; OPREA, I. (IEEE, 2018)
    A 300 GHz source based on discrete Schottky diodes technology is reported in this work. The high frequency part developed by ACST consists of two high power and high efficiency doublers, one at 135-160 GHz and a second one ...
  • High-Power MM-Wave Frequency Multipliers 
    COJOCARI, O.; MORO-MELGAR, D.; OPREA, I. (IEEE, 2019)
    A novel approach has been developed on monolithic integration of Schottky diodes with CVD diamond substrate for improved thermal dissipation. This allowed development of mmwave frequency multipliers with unmatched ...
  • Operation of quasi-optical a THz detectors in heterodyne regime 
    COJOCARI, O.; MARTYANOV, M.; MORO-MELGAR, D.; SOBORNYTSKYY, N. (IEEE, 2017)
    In recent years Schottky-diode technologies gain influence in THz systems because of their large sensitivity, wide range, high power capability and room-temperature operation. Schottky diodes rectify the RF signal directly ...
  • Single-Chip 135-160 GHz Doubler with more than 150 mW Output Power based on Discrete Schottky Diodes 
    MORO-MELGAR, D.; COJOCARI, O.; OPREA, I.; RICKES, M.; HOEFLE, H. (IEEE, 2018)
    Single chip doubler based on novel diamond-based discrete Schottky diodes is presented here. CVD Diamond technology has been integrated by ACST GmbH in the discrete diode structure to implement in high power multipliers ...
