A Yttrium Iron Garnet (YIG) tuned band reject filter using one or more Shunt YIG resonators provides for much wider minimum rejection bandwidths without increasing maximum 3 db bandwidths or spurious response. Various configurations of a tunable shunt YIG tuned band reject filter achieves a wide rejection bandwidth at the low end of the tuning range while keeping the maximum 3 db bandwidth, normally occurring at the high end of the tuning range, to a minimum. |
