Passband Filter30281C IMG

P/N 30281C-1 and 30281C-2 are unique K- and Ku-band filters with extremely narrow passband (less than 0.025%) and wide spurious free stopband (up to 50 GHz). Such a distinctive performance is accomplished by properly combining overmoded cavities with single-mode and evanescent mode cavities. RS Microwave manufacturing experience and technological expedients are crucial to obtain excellent mechanical and thermal stability for these innovative products implementing such extreme filtering functions.
