DESCRIPTION
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 components and lower power consumption. This IC is manufactured using NEC’s 20 GHz fT 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.FEATURES
