Latest Patents
Robert A. Jelen holds a patent for a "High speed phase lock control for frequency switching." This invention describes a digitally controlled microwave phase lock loop that allows for rapid switching from one lock frequency to another. The system converts a digital word corresponding to a desired input voltage into an analog voltage, which is then applied to the coarse tuning port of the loop's voltage-controlled oscillator. Before switching frequencies, the error voltage for the fine-tuning port is compared with a zero error reference voltage. The least significant bit of the digital word is adjusted based on the comparison, allowing for precise control during frequency selection.
