Filters

TRAK Microwave Switched Filter Banks typically include the integration of multiple filter topologies with PIN diode and MMIC switch sub-circuits to achieve operational bandwidths of greater than 3 octaves. Filter topologies include lumped element filters up to 6 GHz and distributed and cavity filter designs up to 20 GHz. Hybrid packaging allows for extremely small sizes, as exemplified by our SP5T switch with outline dimensions of 2.3" X 1.4" X.265".

PN 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.

This PN 61703B-3 is the latest in the RS Microwave Band Rejection filter designed for resolving cosite interference problem with the JTIDSMIDS Band. This filter has very steep transition slopes from passband to stopband (6 MHz is typical.). The unit is constructed as an elliptic air-slab line design, achieving high unloaded Q, which minimizes the insertion loss while maximizing the stopband attenuation.
