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

µPC2757TB features low current consumption and the µPC2758TB features improved intermodulation. From these

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

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.
