Smiths Interconnect is committed to providing technically advanced, high quality “state-of-the-art” RF Filters, Multiplexers, Switched Filter Banks, and Integrated assemblies, from 100 KHz to 65 GHz. All products are subject to the same rigorous design, manufacturing, and inspection criteria. Regardless of the application, our internal process and procedures help ensure that all products are fully compliant to all specifications. Our R & D activities are constantly evaluating new materials, plating techniques, and manufacturing processes to offer the highest performing components available today.
Please use our Filter Select+plus software to select the filter for your application along with S parameter data.
We foster a Culture of Quality to be the best at what we do ... Quality, it is all about the Customer.
In-house capabilities encompass design, development, manufacturing and testing. Providing operational excellence tailored to volume manufacturing requirements, global sourcing, world class engineering talent and rapid prototyping.
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 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 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 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.
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.
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.
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.
Smiths Interconnect is a leading provider of technically differentiated electronic components, subsystems, microwave and radio frequency products that connect, protect and control critical applications in the commercial aviation, defense, space, medical, rail, semiconductor test, wireless telecommunications, and industrial markets.
