Abstract
A method and apparatus which incorporates an optimization gradient algorithm for post production tuning of a microstrip microwave amplifier. The tuning technique replaces conventional time consuming manual post production tuning techniques and comprises a computerized technique which is operable to test the amplifier for its response characteristics, perturb circuit matching elements and measure the response as a result of the perturbations, and thereafter effect the required change in the circuit's tuning elements to bring the circuit response in conformance with a desired value. Perturbation is accomplished by robotic placement of dielectric chips on the matching elements while tuning is accomplished by either computer controlled laser trimming of the lengths of the tuning elements or robotic application of metallization to the tuning elements for increasing their respective lengths.
