NEW:  Series IA Broadband Up/Down Converter

CAES' series IA Broadband Up/Down Converters offer multi-octave frequency conversion for use in modern EW systems. Typical applications include down conversions of the microwave spectrum into a Digital RF Memory (DRFM) and then up-conversion back to the microwave spectrum frequency range.  

In addition, the series IA converters offer a common synthesized local oscillator (LO), low spurious, high dynamic range with fast switching and programmable gain enabling ease of integration into multiple platforms.
