RF Engines launches dynamically re-configurable radio spectrum channeliser

September 23, 2002 -  RF Engines Limited (RFEL), the UK based signal processing specialist, is releasing a radical new patented filter bank design, called Tuneable Pipelined Frequency Transform™ (TPFT) to add to its existing range of high performance real-time signal processing architectures. The new design is being launched at the Communications Design Conference in San Jose, taking place over the week commencing 23 September.

The TPFT allows the user to dynamically select sections of spectrum (channels) of differing bandwidths, from a broad band of spectrum, and to acquire and process these channels in real time. Furthermore, the design disregards the processing of those sections of spectrum that are not of interest, so improving the silicon efficiency even further.

The new architecture has been developed by building upon RFEL's own Pipelined Frequency Transform™ design, and is aimed at those applications that require flexibility in frequency channelisation, but also real-time reconfiguration to different frequency plans.

The TPFT is targeted at a range of applications where reconfigurable front ends are required, from wideband multi-standard receivers e.g. satellite earth station receivers, base station receivers, reconfigurable radio systems through to instrumentation. It is aimed at those applications requiring the channelisation of wideband signals (~80MHz) into different size frequency bins arbitrarily distributed across the input spectrum.

The TPFT gives the users the freedom to tailor the design to their requirements, and allows them to specify channels by centre frequency and bandwidth, to fully define the filter characteristics, and to then reconfigure in real-time to a different frequency plan or plans, as required. Furthermore, spectral shaping masks can also be directly applied onto the outputs within the architecture itself, so allowing even the final filter shapes to be finely tuned to the needs of the application.
