DESCRIPTION

NEC's UPB1008K is a Silicon RFIC especially designed for

handheld low power/low cost GPS receivers. The IC com-

bines an LNA, followed by a double-conversion RF/IF

downconverter block and a PLL frequency synthesizer on one

chip. The second IF Freqency is a pseudo- baseband signal

into a on-chip 2-bit A/D converters.The device can operate on

a supply voltage as low as 2.7 V, and is a housed in a small 36

pin QFN (Quad, Flat, No-lead) package, resulting in a very low

power consumption and reduced board space.

NEC's stringent quality assurance and test procedures en-

sure the highest reliability and performance.
