DESCRIPTION
NEC's UPB1007K is a Silicon RFIC designed for low cost GPS receivers. The IC combines an LNA, followed by a double- conversion RF/IF downconverter block and a PLL frequency synthesizer on one chip. The chip also includes an on-board crystal oscillator working up to 16 MHz which can be used as a CPU reference for fast locking. The device operates on a 3 V supply voltage and is housed in a small 36 pin QFN (Quad Flat No-lead) package, resulting in low power consumption and reduced board space. The device is manufactured using the state of the art UHS0 25 GHz f T silicon bipolar process. NEC's stringent quality assurance and test procedures en- sure the highest reliability and performance.
