Aldo E. Linsenbardt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Receiver protector with multi-level STC attenuation
    Patent number: 4371851
    Abstract: A radar receiver protector having high isolation and low insertion losses due to a unique microwave assembly configuration is disclosed. The receiver protector includes at least one high power input protection stage and a sensitivity time controlled multi-level attenuation which together achieve rapid switching with a non-critical bias supply and circuit configuration and develop attenuation levels which are invariant with temperature and insensitive to diode parameters.
    Type: Grant

  • Broadband, upper sideband terminated, low-noise parametric amplifier
    Patent number: 3992675
    Abstract: A parametric amplifier which includes series coupled diodes contained in a resonating wave guide for providing a low noise figure by limiting the impedance to the idler circuit and inhibiting current flow in the upper sideband circuit. The mechanism for inhibiting current flow of the upper sideband circuit is independent of the characteristic impedance of the resonating wave guide to provide a constant, low power requirement, with high gain and broadband performance.
