Title: Bret A Herscher: Innovator in Microwave Power Measurement
Introduction
Bret A Herscher is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of microwave power measurement, holding a total of 3 patents. His work focuses on developing advanced systems that enhance the accuracy and performance of power measurements.
Latest Patents
Herscher's latest patents include a "Swept Microwave Power Measurement System and Method." This innovative system is capable of performing accurate high-performance absolute power measurements on the fly, integrating seamlessly with a scalar analyzer. The system interpolates a calibration factor of the detector at a given frequency point in the sweep, utilizing previously established calibration factors stored in memory. This allows for the determination of an 'apparent' power level of the input signal at a standard frequency, which is then adjusted to find the 'absolute' power level.
Another significant patent is the "True RMS Power Demodulation System and Method for a Modulated RF Signal." This system employs a DC coupled linear amplifier and linearizes the diode detector prior to demodulation. The resulting demodulated signal is proportional to the difference of RF powers, ensuring that the network measurement remains unaffected by modulation depth, RF feedthrough, or the presence of interfering signals or noise.
Career Highlights
Throughout his career, Herscher has worked with prominent companies such as Wavetek Microwave, Inc. and Wavetek Corporation. His experience in these organizations has contributed to his expertise in microwave technology and power measurement systems.
