Bandstop CONTACT SALES Combline Filters BSC Filters’ Combline filters use a variety of wavelength capacitively loaded rods as resonators offering a low loss, rugged and compact design. Giving a large degree of parameter flexibility, Combline filters can be optimised for size, insertion loss or stopband performance. By altering rod sizes from a thirtieth to a quarter of a wavelength a variety of filter requirements can be realised. Frequency Range : 150MHz to 16GHz Bandwidth : 1% to 35% Stopband : Up to 9 times fc Cavity Filters For applications where low insertion loss and high performance are important. Cavity structures can be used to realise bandpass or bandstop filters and multiplexers where they can be used exclusively or integrated with other structures as the application requires. BSC have considerable experience in mechanical applications and are often employed to design the outline package for custom integration within the application saving on size and cost, whilst meeting tough environmental requirements. Cavity structures give high Q performance, whilst the mechanics employed make them suitable for Military and Commercial applications where narrow bandwidth and ruggedness are important parameters. Cross coupling is used to greatly improve selectivity, whilst maintaining low Insertion Loss. Cavities can be supplied as individual filters or integrated into banks or sub-assemblies. For broader stopband performance cavity structures can be combined with Tubular, Lumped Element, Suspended Substrate or Combline filters. Scope Frequency Range: 500MHz to 15GHz Bandwidth: 1% to 10% Stopband: up to 4 times Fc Structures Bandpass Bandstop Multiplexers Hybrids Temperature compensation Applications WiMax Base Station Test Equipment Send Enquiry Lumped Element Filters Using the very latest filter design techniques BSC’s Lumped Element filters exhibit low insertion loss, good VSWR and steep-skirt selectivity. This type of structure is very versatile and well suited to a variety of market applications, including Broadcast, Telecommunications, SatComs & Defence and is available in a variety of filter configurations. Highpass Lowpass Bandpass Notch Multiplexer UHF – VHF Frequency Range: 300kHz to 3GHz Bandwidth: 1% to multi-octave Stopband: up to 10 times Fc Suitable for Lowpass/Highpass/Bandpass, Notch & Multiplexer devices SMT or connectorised package options available Suspended Substrate Filters Suspended Substrate StripLine (SSS) filter technology enables high frequency (up to 40GHz) broadband filters to be realised utilising elliptical responses for excellent close-in rejection. SSS technology utilises a photo-etched, copper-clad dielectric substrate (usually PTFE) secured between silver plated machined casings, to provide outstanding performance in terms of high Q and low insertion loss, combined with a small, lightweight yet rugged construction. This type of filter is ideally suited to broadband applications such as Electronic Warfare systems (ECM, ESM & ELINT). SSS design capability covers the full range of filter structures.

Scope Frequency Range: 2 GHz to 18 GHz Bandwidth: 5% to Multi-octave Topologies Bandpass Lowpass Highpass Bandstop Applications Phased Arrays UAVs and Missiles High-volume Applications Small-size, Low-mass Applications Temperature-stable Applications Miniaturisation of RF Filtering requires an entirely specialised approach to design and manufacture. Surpassing conventional Thin Film technology, BSC utilises materials that offer significant advantages over the traditional Alumina solutions, with improved size, loss, temperature stability and manufacturing repeatability. For surface-mount applications where real-estate is critical, BSC Thin Film devices offer performance otherwise unachievable in such a small space. Unique high-k substrates enable high-Q filters to be realised many times smaller than more traditional ceramic or air dielectric-based structures. Thin Film devices offer SAW-style miniaturisation, operating up to 18 GHz, and offering much greater bandwidths. The manufacturing process involves tight control and characterisation of the substrate material using highly refined, proprietary techniques. Stringent processing procedures control the tolerances required during manufacture to necessitate absolute accuracy; this in turn precipitates repeatability. Thin Film solutions are attractive not only for their miniaturisation but for high-volume applications in mass-produced modules or phased array antennas.

These provide the optimum solution for applications where low insertion loss or high power handling are important, for example RADAR applications with power handling requirements in excess of 60kW. BSC Filters’ Exact Technology allows filters to be designed and manufactured using Iris construction which offers significant advantages for volume manufacture. Further reductions in costs are afforded by BSC Filters’ expertise: Casting CNC Machining Extruded Iris We are able to deliver waveguide products in a variety of formats and finishes, and our specially developed software allows us to offer “right first time” design of waveguide filters and diplexers, reducing development cost and time to market.
