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.
