摘要： A method is presented where the phase trace is offset for each sweep such that the first point is always at zero degrees. The resulting traces are then averaged. The average reduces the noise in the phase trace and results in a less noisy group delay trace.

摘要： The present invention tunes a coupled resonator filter to a given tuning specification using a reference filter that was previously tuned to the specification. A method of tuning a subject filter comprises determining a frequency change for each resonator of the subject filter and applying each determined change to the respective resonator, such that the subject filter is tuned to the specification. The frequency changes are determined from frequency-pushing interactions between combinations of resonators in either the reference or subject filter. A system for tuning the subject filter comprises a measurement system, a tuning program stored in a system memory, and a controller that controls the measurement system and executes the tuning program. The tuning program comprises instructions that preferably implement the tuning method. A tuned coupled resonator filter comprises a plurality of resonators that are adjusted in accordance with the method or using the tuning system.
