Patent number: 11329718Abstract: An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications capable of flexibly processing high-bandwidth and low-bandwidth RF input signal(s). The RF transceiver may selectively distribute high-bandwidth RF input signals among one or more DSP pipelines for parallel processing of the RF input signals, and the RF transceiver may coherently recombine the processed signals from the one or more DSP pipelines to generate an RF output signal. The ADDA RF transceiver includes one or more ADCs, DSPs, and DACs, all on one or more ASICs, FPGAs, or modular electronic devices in a single semiconductor package. Further, the RF transceiver is radiation tolerant at the module, circuit, and/or system level for high availability and reliability in the ionizing radiation environment present in the space environment.Type: GrantFiled: January 6, 2021Date of Patent: May 10, 2022Assignee: Seakr Engineering, Inc.Inventors: Paul Rutt, Erik Buehler, Damon Van Buren

Patent number: 10771145Abstract: A satellite communication system processes a plurality of input signals to generate beamformed signals, drives a plurality of nonlinear power amplifiers with the beamformed input signals to produce RF signals for transmission; and transmits the RF signals with a plurality of Tx antenna elements. Conversion to and from linear signals to and from nonlinear or digitized signals is performed. Temporal or spatial decorrelation of the beamformed signals is employed to reduce the impact of intermodulation products. In some cases the power amplifiers are nonlinear, and can be one-sided or two-sided and produce two or three distinct output levels.Type: GrantFiled: March 10, 2017Date of Patent: September 8, 2020Assignee: SEAKR ENGINEERING, INC.Inventor: Erik Buehler

Patent number: 10594385Abstract: An electronic device for a communications satellite for beamforming, channelization, and/or routing is implemented using a digital folded architecture to reduce the number of serial communication paths and provide more flexible routing and network configurability and scalability. A method for configuring the switching network of a system comprising multiple electronic devices allows the system to be dynamically reconfigured to implement different types of networks.Type: GrantFiled: April 4, 2018Date of Patent: March 17, 2020Assignee: SEAKR ENGINEERING, INC.Inventors: Erik Buehler, Richard E. Perego

Patent number: 9690646Abstract: Light-weight, configurable error detection in a satellite communication system that detects invalid SerDes lanes via hash codes appended to packets of data in the lanes. An indication can be passed back upstream about the invalid lane so that the lane can be reset. Error correction can be provided by reconstructing the bit data in the invalid SerDes lane based on parity information in an optional parity lane.Type: GrantFiled: July 29, 2015Date of Patent: June 27, 2017Assignee: SEAKR ENGINEERING, INC.Inventor: Erik Buehler
