Filter Select Plus

Smiths Interconnect filters are available to suit a wide range of applications in the military, commercial and aerospace fields. For more information, please see the notes for each filter topology.Superior performance is achieved through the use of high "Q" components and computer modeling.

For band-reject filters, please contact the factory.

 

Planar X Filter Series

Planar X Series of standard RF filters provide system engineers with high performance, compact, light-weight solutions for critical RF filtering in X-band, Ku-band, and Ka bands. Planar X Series compliments Smiths Interconnect’s broad portfolio of RF/Microwave components with an off-the-shelf product reducing the lead times of custom designs.

Cavity Filters

Cavity filter designs are available in the frequency range of 30 MHz to 51 GHz and with bandwidth options from less than 0.5% to over 66%. Cavity filters offer the user very low insertion loss, steep skirt selectivity, and narrower bandwidths than discrete component filters. Smiths Interconnect’s waveguide filters provide low-loss solutions for high power applications.  Waveguide filter operating frequency ranges from 1 to 100 GHz and can be offered with temperature stable materials.

Ceramic Filters

Ceramic Filters are manufactured in two basic styles for both commercial and military applications. The high-volume, cost-effective units in open frame, non-hermetic packages are most often used in commercial applications. The lower volume, custom designed hermetic packages find wide usages in military applications. Both styles are available from UHF to C-band and in various mounting configurations. In both instances the same high “Q” coaxial resonators are used which yield low insertion loss and excellent stability over temperature. A low ripple Chebyshev transfer function is standard with bandpass filters, notch filters and diplexer available.

Discrete Filters

Miniature discrete component filters are available from HF to X-band and are designed to give optimal performance where small size is critical. Electrical and mechanical requirements for each design are computer-generated, taking into consideration realizable “Q” and environmental conditions, then analyzed using our unique software, thereby reducing the amount of trial-and-error alignment.

RF Filters and Diplexers

Series of discrete lumped element filters and diplexers with standard “off the shelf” packaging utilizing the same internal components, circuit topologies and transfer functions found in Lorch filter products manufactured for military and space applications. Standard units are an ideal choice when hermetic sealed packages are not a requirement and when lower cost and quick delivery are essential.

RF Tunable Filters

Tunable filter products are available from HF to S-band and are designed to provide high performance in a single package. While typically used in test and measurement applications, these products can also be ruggedized for mobile and remote applications.
