... BLOCK DIAGRAM 1 : PIN 1 – 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 ...
