RF/IF FREQUENCY DOWN-CONVERTER +
PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER
DESCRIPTION
The µPB1007K is a silicon monolithic integrated circuit for GPS receiver. This IC is designed as double
conversion RF block integrated Pre-Amplifier + RF/IF down-converter + PLL frequency synthesizer on 1 chip.
This IC is lower current than the µPB1005K and packaged in a 36-pin QFN package.
This IC is manufactured using our 30 GHz fmax UHS0 (Ultra High Speed Process) silicon bipolar process.
