He holds 4 patents that showcase his innovative contributions to the field. His work primarily revolves around enhancing the performance and reliability of multi-band receivers.

Latest Patents

One of Landmark's latest patents is titled "Method and apparatus for on-demand interference rejection in multi-band GNSS receivers." This invention relates to an adaptive intermediate frequency (IF) filter designed for multiband receivers. The adaptive IF filter can be dynamically configured to operate as either a low-pass or a complex band-pass architecture. This flexibility allows the receiver to maintain its multiband functionality under normal conditions while dynamically switching to a single-frequency band with high resistance to jamming during severe interference. This approach is particularly beneficial for GNSS receivers, as temporary signal loss is less critical compared to cellular transceivers.

Another significant patent is for a "Receiver with overloading protection/prevention." This invention includes an antenna that receives signals across multiple frequency ranges and a series of amplifiers tailored to amplify these signals. Each receive path is equipped with a power detector that monitors signal strength and a switch that can deactivate the path if an overload condition is detected. This design enhances the reliability and performance of the receiver in challenging environments.
