BIPOLAR ANALOG + DIGITAL INTEGRATED CIRCUIT

µPB1008K

REFERENCE FREQUENCY 27.456 MHz, 2ndIF FREQUENCY 132 kHz

RF/IF FREQUENCY DOWN-CONVERTER +

PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER

DESCRIPTION

The µPB1008K 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 has IQ recovery function, builds a 2-bit A/D converter in both I channels and Q channels, respectively, and

carries them in 36-pin plastic QFN package.

This IC is manufactured using our 30 GHz fmax UHS0 (Ultra High Speed Process) silicon bipolar process.

FEATURES

• Double conversion

• Integrated RF block

• Needless to input counter data

• VCO side division

• Reference division

• Supply voltage

• Low current consumption

• Gain adjustable externally

• Power-save function

• High-density surface mountable

: fREFin = 27.456 MHz, f1stIFin = 175.164 MHz, f2ndIFin = 132 kHz

: Pre-Amplifier + RF/IF frequency down-converter + PLL frequency synthesizer

: The 2-bit A/D converter is unified to single chip.

: fixed division internal prescaler
