DESCRIPTION
The
μ
PC8112T is a silicon monolithic integrated circuit designed as 1st frequency down-converter for
cellular/cordless telephone receiver stage. This IC consists of mixer and local amplifier. Due to optimized circuit
current, the
μ
PC8112T improves RF performance such as intermodulation, leakage and linearity compared with
conventional Si MMIC of the
μ
PC2757T and
μ
PC2758T. The
μ
PC8112T features 3 V supply voltage and mini mold
package which contribute to make system lower voltage, space decreased and fewer components.
The
μ
PC8112T is manufactured using NEC’s 20 GHz f
T
NESATIII 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
