CXA3355ER GPS Down Converter IC

CXA3355ER GPS Down Converter IC

The CXA3355ER is an IC developed as a GPS RF down converter. This IC realizes a reduction in the number of external parts by integrating an LNA, image rejection mixer, IF filter, PLL and VCO (L, C) into a small package with low current consumption. Features • Includes all functions required for the .
