SILICON MMIC 1st FREQUENCY DOWN-CONVERTER

FOR CELLULAR/CORDLESS TELEPHONE

DESCRIPTION

The µPC2757TB and µPC2758TB are silicon monolithic integrated circuit designed as 1st frequency down-

converter for cellular/cordless telephone receiver stage. The ICs consist of mixer and local amplifier. The

PC2757TB features low current consumption and the µPC2758TB features improved intermodulation. From these

µ

two version, you can chose either IC corresponding to your system design. These TB suffix ICs which are smaller
package than conventional T suffix ICs contribute to reduce your system size.

The µPC2757TB and µPC2758TB are manufactured using NEC’s 20 GHz fT NESAT™||| silicon bipolar process.
This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from
external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.

FEATURES

• Wideband operation : f

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

• Low current consumption : ICC = 5.6 mA TYP. @ µPC2757TB

• Supply voltage : VCC = 2.7 to 3.3 V

• Minimized carrier leakage : Due to double balanced mixer

• Equable output impedance : Single-end push-pull IF amplifier

• Built-in power save function

RFin

= 0.1 to 2.0 GHz, f

ICC = 11 mA TYP. @ µPC2758TB

IFin

= 20 to 300 MHz

APPLICATIONS

• Cellular/cordless telephone up to 2.0 GHz MAX. (example: GSM, PDC800M, PDC1.5G and so on): µPC2758TB

• Cellular/cordless telephone up to 2.0 GHz MAX. (example: CT1, CT2 and so on): µPC2757TB
