UPB1005GS
DESCRIPTION
The µPB1005GS is a silicon monolithic integrated circuit for GPS receiver. This IC is designed as double conversion RF block integrated RF/IF down-converter + PLL frequency synthesizer on 1 chip. The µPB1005GS features shrink package, fixed prescaler and supply voltage. The 30-pin plastic SSOP package is suitable for high density surface mounting. The fixed division internal prescaler is needless to input serial counter data. Supply voltage is 3 V. Thus, the µPB1005GS can make RF block fewer ponents and lower power consumption. This IC is manufactured using NEC’s 20 GHz f T NESATTMIII silicon bipolar process. This process uses direct silicon nitride passivation film and gold electrodes. These materials can protect the chip surface from pollution and prevent corrosion/migration. Thus, this IC realizes excellent performance, uniformity and reliability.
