CXA3355TQ

GPS Down Converter IC

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)
