Title: David Alan Metz: Innovator in RF Power Calibration
Introduction
David Alan Metz is a notable inventor based in McMinnville, Oregon. He has made significant contributions to the field of radio frequency (RF) power calibration. With a total of 3 patents, Metz has developed innovative solutions that enhance the efficiency and effectiveness of RF systems.
Latest Patents
One of his latest patents is the Modular Recipe Controlled Calibration (MRCC) apparatus, which is designed to balance plasma in a multiple station system. This invention includes a circuit tuning RF power that features a low to mid frequency (LF/HF) tuning circuit. The circuit comprises a variable LF/MF capacitor coupled in series with an LF/MF inductor. The LF/MF tuning circuit is strategically coupled between ground and a common node that is configured to receive an RF input. Additionally, the circuit incorporates a high frequency (HF) tuning circuit that is connected in parallel to the LF/MF tuning circuit. This HF tuning circuit includes a variable HF capacitor coupled in series with an HF inductor. Notably, cross parallel isolation occurs between the LF/MF inductor of the LF/MF tuning circuit and the HF inductor of the HF tuning circuit when adjustments are made to the variable LF/MF capacitor or variable HF capacitor.
