Broadband Components
Broadband
BSC design and manufacture a wide range of suspended substrate Stripline filters that are used in a variety of receiver protect and scanning applications. These devices are generally designed to withstand the harshest of requirements.
Suspended Substrate Stripline (SSS) filters offer unrivalled broadband performance offering exceptionally low loss and low ripple over multi-octave bandwidths with excellent rejection levels of greater than 60dB extending far beyond the required Passband. In addition to band Pass filters, Notch filters, Band-reject, High-pass, Low-pass and complex multiplexers can also be realised. BSC Filters Ltd are world leaders in SSS filter technology offering a broad range of products ideally suited to Defence environments. Products can be specified to cope with extreme temperature ranges of -55 degC to +85 degC and harsh environmental requirements such as those found in 4th generation fighter aircraft as well as Naval surface and sub-surface applications. Typical applications for these products include Electronic Support Measures (ESM), Electronic Counter measures (ECM) and more generic Electronic warfare (EW) receivers. The physical nature of the technology also lends itself to higher levels of integration by incorporation of switches, amplifiers etc within the SSS medium to offer more complex products such as broadband EW switched Filter banks and Switched Multiplexers.
