Jack Edwin Lundstedt, Jr. 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).

  • Patent number: 11979176
    Abstract: In some implementations, a communication device, includes a printed circuit board comprising conductors routed to support a plurality of different configurations of modulation and/or demodulation functionality. The printed circuit board can have multiple analog output interfaces and one or more analog input interfaces, multiple digital network interfaces, and sockets for components including a controller, multiple processors, digital-to-analog converters (DACs), and an analog-to-digital converter (ADC). Various processor sockets are interconnected to support the processors in different sockets selectively being used for different functions, e.g., as a modulator, burst processor, channelizer, etc.

  • Publication number: 20230070699
    Abstract: In some implementations, a satellite gateway includes a set of modulators comprising (i) a first modulator to modulate signals for transmission using a first of multiple polarizations, and (ii) a second modulator to modulate signals for transmission using a second of the multiple polarizations. The satellite gateway includes a set of upconverters comprising at least one upconverter for each of the multiple polarizations, wherein each of the upconverters is configured to generate a radiofrequency output by concurrently upconverting multiple intermediate frequency inputs to different frequency ranges. The satellite gateway includes an intermediate frequency distribution network configured to distribute the multiple intermediate frequency output signals from each of the modulators to the inputs of the upconverters. The satellite gateway includes a set of radiofrequency switches that are operable to selectively provide the radiofrequency outputs of the upconverters to antenna feeds for the multiple polarizations.

  • Publication number: 20230074318
    Abstract: In some implementations, methods, systems, and apparatus, including machine-readable media storing executable instructions, are provided for switching radio frequency chains. For example, a gateway for a satellite communication system can include a first radiofrequency chain, a second radiofrequency chain, and a third radiofrequency chain configured to operate in a standby mode. The gateway includes radiofrequency switches configured to (i) switch between coupling the first radiofrequency chain and the third radiofrequency chain to a first antenna feed for the first channel, and (ii) switch between coupling the second radiofrequency chain and the third radiofrequency chain to a second antenna feed for the second channel. The gateway also includes a controller configured to monitor the status of the radiofrequency chains and, based on the monitored status, instruct the radiofrequency switches to switch between different connections of the radiofrequency chains with the antenna feeds.

  • Patent number: 11336493
    Abstract: A system includes a processor and a memory. The memory stores instructions executable by the processor to identify an equalization response for equalizing an output signal of a modulator of a satellite gateway, generate a compensation response based on the equalization response and a sample rate of a pre-distorter of the modulator, and send the equalization response to the pre-distorter.
