Title: Innovations of James Knecht in Satellite Technology
Introduction
James Knecht is a notable inventor based in San Jose, CA, who has made significant contributions to satellite technology. He holds a total of 4 patents that showcase his expertise in the field. His work primarily focuses on improving the calibration processes of satellite beamforming channels.
Latest Patents
Knecht's latest patents include a multiport amplifier input network designed to compensate for output network gain and phase frequency response imbalance. This innovation allows for the calibration of satellite beamforming channels using a low power, spread spectrum calibration signal. The calibration signal operates below the noise level of a user signal in an active channel, enabling channels to be calibrated while they are in use. The calibration process involves a two-stage approach, first calibrating the output hybrid matrix and then the entire transmit side circuitry. Additionally, the dwell time spent on calibrating a channel can be adjusted based on the power of the user signal present. To facilitate this process, a transmit probe is utilized to inject a calibration signal into the receive antennas, while a receive probe extracts the calibration signal from the transmit antennas. To minimize the frequency of calibrations, the methods can be based on path-to-path differences, which are also applicable to multiport amplifiers.
