Title: Walter H Kehler: Innovator in Oscillator Technology
Introduction
Walter H Kehler is a notable inventor based in Sunrise, FL (US), recognized for his contributions to oscillator technology. He holds a total of 11 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest inventions is the "Self-calibrating oscillator system," which comprises a voltage-controlled oscillator (VCO). This system includes a single input, a power input, and an oscillation input. The oscillation input is connected to an amplitude detection device that provides an indication of the output amplitude of the VCO to a threshold detect module. Based on the threshold detected, a threshold indicator is sent to a voltage supply module, allowing the voltage powering the VCO to be adjusted according to the threshold indicator's value. Another significant patent is the "Method and apparatus for calibrating a local oscillator in a direct conversion receiver." This invention features a receiver with a main loop and a secondary loop, where the receiver phase locks an incoming RF signal momentarily. It then samples and stores a correction voltage applied to the main VCO, which is used to calibrate the local oscillator frequency to match the incoming RF signal frequency.
