Title: The Innovations of Patrick David Jeffers
Introduction
Patrick David Jeffers is a notable inventor based in Chandler, AZ. He holds 2 patents that showcase his contributions to the fields of amplification circuits and satellite communication systems. His work reflects a commitment to advancing technology and improving communication methods.
Latest Patents
One of Jeffers' latest patents is for a "Constant-phase, gain-controlled amplification circuit." This invention is designed for use in radio receivers, achieving both constant phase shift over the gain range and low intermodulation. The circuit includes a gain-controlled amplifier optimized for good fidelity, even if it sacrifices some phase linearity. A phase shift compensator is integrated to address phase non-linearity by imposing a variable delay downstream of the amplifier. This delay is determined by a gain-control signal generated by an Automatic Gain Control (AGC) circuit, which translates through a look-up table into delay values that control a programmable delay element. The adjusted clock signal produced by this element drives a digitizer that digitizes and delays the amplified signal.
Another significant patent by Jeffers is titled "Method and apparatus for providing additional resources in a satellite." This invention enhances satellite communication systems by utilizing seam satellites that connect with existing communication satellites through previously unused crosslinks. These seam satellites are strategically positioned between orbital planes, allowing them to provide new services such as earth sensing and observation. They can also serve as attachment points for new space-based users, facilitating communication with existing units.
