DESCRIPTION
The UPB1004GS is a Silicon Monolithic Integrated Circuit
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 fT silicon bipolar process.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
