Latest Patents

Among his latest innovations, Gumm has developed two noteworthy patents. The first, titled **Simultaneous ACLR Measurement**, describes a system designed for simultaneous measurements of Adjacent Channel Leakage Ratio (ACLR) across multiple wireless communication channels. This innovative approach utilizes dual channel processing, where an input signal is downconverted to generate a wideband signal that is processed at both high speed with a low-resolution ADC and low speed with a high-resolution ADC. The processed data streams are then analyzed by a Digital Signal Processor (DSP) to achieve precise simultaneous ACLR measurements.

The second, **Self-Adjusting I-Q Modulator System**, enhances the calibration processes for quadrature modulated carrier outputs. This system incorporates a waveform acquisition circuit to gather a comprehensive waveform, allowing for accurate amplitude and phase measurements. The calibration involves adjusting variable offset voltages to nullify the modulated output, and iteratively tailoring the phase shifters to ensure that the outputs maintain a quadrature relationship. This meticulous process ensures reliability and accuracy in signal modulation, which is crucial for efficient communication.
