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.

FEATURES

• Double conversion

: fREFin = 16.368 MHz, f1stIFin = 61.380 MHz, f2ndIFin = 4.092 MHz

• Integrated RF block

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

• Needless to input counter data

: fixed division internal prescaler

• VCO side division

:

÷200 (÷25, ÷8 serial prescaler)

• Reference division

:

÷2

• Supply voltage

: VCC = 2.7 to 3.3 V

• Low current consumption

: ICC = 25.0 mA TYP. @ VCC = 3.0 V

• Gain adjustable externally

: Gain control voltage pin (control voltage up vs. gain down)

• On-chip pre-amplifier

: GP = 15.5 dB TYP. @ f = 1.57542 GHz

NF = 3.2 dB TYP. @ f = 1.57542 GHz

• Power-save function

: Power-save dark current ICC(PD) = 5

µA MAX.

• High-density surface mountable

: 36-pin plastic QFN

APPLICATIONS

• Consumer use GPS receiver of reference frequency 16.368 MHz, 2nd IF frequency 4.092 MHz (for general use)
