A synthesis based approach to automated filter tuning

The process described here has been verified on data obtained from simulations and on real filters currently in production at Filtronic Comtek; the results have been extremely promising and the process is being incorporated into production lines. The initial system is a guidance system for human operators and allows the devices to be aligned faster than the average technician can achieve without guidance. If the filter to be aligned can be measured accurately, the device structure is known and a synthesis procedure for the structure is known then the procedure can be applied with success. (3 pages)
