DATA SHEET

BIPOLAR ANALOG + DIGITAL INTEGRATED CIRCUIT

µPB1005GS

REFERENCE FREQUENCY 16.368 MHz, 2ND IF FREQUENCY 4.092 MHz

RF/IF FREQUENCY DOWN-CONVERTER +

PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER

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 components and lower power

consumption.

This IC is manufactured using NEC’s 20 GHz f^TNESAT^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.
