Title: Innovations by Steven Rajkowski in RF Amplifier Technology
Introduction
Steven Rajkowski is an accomplished inventor based in East Kingston, NH (US). He holds 2 patents that showcase his expertise in radio frequency (RF) amplifier technology. His innovative designs focus on enhancing the performance and efficiency of RF amplifiers, making significant contributions to the field.
Latest Patents
One of Rajkowski's latest patents is for a "Low swap circuit card design for RF power amplifiers." This invention introduces a system and method for utilizing an embedded microprocessor in an RF amplifier. The microprocessor eliminates the need for manual calibration by collecting initial amplifier performance data based on a set of parameters and calculating necessary corrections. It adjusts levels within the circuit to achieve optimal operating points. The embedded microprocessor sets voltage levels with internal circuitry and communicates this information externally through a serial communication port, allowing users to monitor and readjust internal bias levels as needed. This innovation provides calibration, self-testing, and monitoring capabilities for the RF amplifier, functioning as a bias and temperature compensation controller.
Another significant patent by Rajkowski is the "Ultra-wideband high power amplifier architecture." This invention discloses techniques and architecture for providing an ultra-wideband, multi-channel solid-state power amplifier. The architecture includes a power divider that splits an input signal and delivers it to multiple downstream channel chipsets. Each chipset amplifies a sub-band of the original full-band input signal, resulting in coverage of the same ultra-wideband frequency range. This design offers high RF power with excellent amplifying efficiency and ultra-wide instantaneous frequency bandwidth performance in a compact package.
