800 MHz INPUT DIVIDE BY 2, 4 PRESCALER IC FOR PORTABLE SYSTEMS

The µPB1511TB is a silicon monolithic integrated circuit designed as a divide by 2, 4 prescaler IC for portable radio systems. This IC is manufactured using NEC’s 30 GHz fmax UHS0 (Ultra High Speed Process) silicon bipolar process.

Consequently, this IC is lower circuit current and smaller package than conventional µPB1509GV.

FEATURES

• Operating frequency : fin = 50 to 700 MHz @ ÷ 2,

50 to 800 MHz @ ÷ 4

• Low current consumption : 3.5 mA @ VCC = 3.0 V

• High-density surface mounting : 6-pin super minimold

• Supply voltage : VCC = 2.4 to 3.3 V

• Selectable division : ÷ 2, ÷ 4

APPLICATIONS

• Portable radio systems

• Cellular/cordless telephone 2nd local prescaler
