This data sheet describes the principle, characteristics and application of µPB1005K. This IC is a double conversion RF block integrated RF/IF down-converter + PLL frequency synthesizer IC for GPS receiver. This IC uses 36-pin plastic QFN package, fixed prescaler and supply voltage. This IC is manufactured using NEC’s 20GHz fT NESAT TMIII 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.
