RF Engines has extended the range of its Digital Down Converter (DDC) technology so that it can now process up to 1GHz of bandwidth (2Gsps ADC rate) input and provide a narrower band output.

This technology can operate with fixed frequencies and bandwidths or be fully flexible as required.

One of the main application areas is for electronic surveillance in military digital receivers, where this approach enables a desired signal band to be extracted from a wide slice of the spectrum in order that further analysis of the signal content can be carried out.

For example, a radar warning receiver can rapidly spot the signal ‘signature’ of an incoming missile or other threat, and the down converter will extract the specific signal and measure its parameters.

In scientific applications, for example in radio telescopes, this approach allows wide sections of the spectrum to be monitored at one time in order to acquire weak or hidden signals.

The RF Engines Wideband DDC core is highly optimised for size and speed, on a range of Xilinx or Altera FPGA devices.

With options such as fractional re-sampling for arbitrary output bandwidth selection and the ability to implement the design in either logic-rich or DSP-rich FPGA architectures, the RF Engines Wideband DDC will meet the needs of a variety of applications.

The company is also committed to offering a portfolio of DSP IP cores and as such as engaged to research DDC designs in the +10GHz range.
