BIPOLAR ANALOG INTEGRATED CIRCUITS
µPC2757TB, µPC2758TB
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
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 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.
