Method for tuning the response of RF and microwave devices

摘要: A method of tuning a microwave or RF circuit is given which comprises the steps taking (20) located in casing (57), said comprising housing portion (32) and window (50), (50) being substantially conducting at microwave/RF frequencies, least one area that transparent optical frequencies and, directing laser beam (66) onto through so as to alter material properties selected areas (20). This permits circuits, including filters, be tuned without need for screws.
