Latest Patents

Kowalik holds a patent for an "Estimator for estimating an operating defect in a quadrature modulator." This invention includes two mixers that apply respective carrier and modulating signals. The output signals from these mixers are directed to a summing circuit, creating a modulated signal. The estimator features detection circuitry that measures the instantaneous power of the modulated signal. Additionally, it includes multiplication circuitry that multiplies the detected power by at least one of the modulating signals. Integration circuitry is also part of the design, which integrates the multiplication result and provides a signal indicative of the modulator's operating defect. This technology is particularly useful for eliminating residual carrier signals in the modulated output and correcting quadrature discrepancies between the mixer outputs.
