    CW GaAs MITATT source on copper heatsink up to 160 GHz

    Electronics Letters, vol. 30, no. 16, pp. 1316-1317

    Abstract anzeigen

    The performance of a GaAs pn-junction transit time device with mixed tunnel-avalanche breakdown is described. At 164 GHz a CW output power of 1 mW has been achieved in the fundamental mode with devices on copper heatsink. This is to date the highest frequency achieved with CW GaAs diodes. The corresponding noise measure is 28 dB at 160 GHz

    A comparative study on the noise measure of millimetre‑wave GaAs IMPATT diodes

    Solid-State Electronics, vol. 37, no. 3, pp. 427-431

    1994

    Abstract anzeigen

    It is theoretically and experimentally demonstrated that the small-signal noise measure of Gaas single-drift Impatt-diodes can efficiently be reduced by increasing the total width of the diode space-charge region due to shot-noise reduction and space-charge smoothing. For a total space-charge region width of 770 nm, a minimum noise-measure of 22 dB at 60 GHz is obtained. This value reaches almost the theoretical optimum noise measure of pin-avalanche diodes.
