DESCRIPTION
The UPB1005GS is a Silicon RFIC designed for low cost GPS
receivers. The IC combines a double-conversion RF/IF
downconverter block and a PLL frequency synthesizer on one
chip. The device operates on a 3 V supply voltage and is
housed in a small 30 pin SSOP package, resulting in low
power consumption and reduced board space. The device is
manufactured using the NESAT™
III 20 GHz f
T
silicon bipolar process.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
USAGE
• CONSUMER USE GPS RECEIVER OF REFERENCE
FREQUENCY 16.368 MHz, 2ND IF FREQUENCY 4.092
MHz.
