In addition, almost any value of rejection bandwidth can be provided. Furthermore, selecting a number of sections and coupling iris dimensions will be required. Pass-band insertion loss minimizes with the use of 11.5” high-Q aluminum cavities. Temperature stability is also provided by invar tuning rods on copper center conductors.
