CXA3355AER

GPS Down Converter IC

Description

The CXA3355AER 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.

(Applications: GPS down converter IC)
