RadioScape's Single Chip RF Front-End Integrates Six Frequency Bands

London, UK -- RadioScape has created what the company claims is the first, software-controlled, single chip RF front end that can handle six frequency bands -- Band III and L-Band for Digital Audio Broadcasting (DAB), medium wave, long wave and short wave for AM and Digital Radio Mondiale (DRM), and Band II for FM. The RF chip combines with a standard DSP chip that runs RadioScape's baseband digital radio software and also controls the RF IC to form a two chip solution.

"This new RF IC is a breakthrough technology for RadioScape that will revolutionise multistandard, multi-band digital radio," said John Hall, RadioScape's CEO. "There is nothing like it in the market and is the result of a major initiative that we started over two years ago to create a technology platform for our next generation consumer radios. The objective was to create a highly flexible RF device that would complement our software-defined radio approach, timed to coincide with the emerging DRM market, and we have done that."

"Our unique partitioning of the radio system allows us maximum re-use of the digital components by loading only the appropriate baseband stack into the DSP as and when required." explained Dave Hawkins, VP of Business Development at RadioScape. "We have used the same approach in our RF IC, which reuses internal functionality to best suit the frequency band and standard required at the time. Dynamic configuration of the RF path on the RF IC is controlled by the DSP using software algorithms to ensure the optimisation of both performance and power consumption. The result is a multi-frequency RF device that requires less than half the power used by the equivalent circuits in our current generation of multi-standard modules."

Available only in a RadioScape module offering, the RF IC will be used to create a new range of modules that maintain the size and pin configurations of existing modules. RadioScape's RS200 family provide highly optimised DAB and FM reception whilst the RS500 family provides additional features and functionality, such as fully integrated Digital Radio Mondiale and AM reception, in addition to DAB and FM. Full details of the new RF IC-enhanced modules will be available shortly along with samples in June.
