GPS Down Converter IC
CXA3355TQ
Description
The CXA3355TQ is an IC developed as a GPS RF down converter.
This IC realizes a reduction in the number of external parts by integrating LNA, image rejection mixer, IF filter
and PLL/VCO parts, such as inductor and variable capacitors.
(Applications: GPS RF down converter IC)
Features
