PRELIMINARY DATA SHEET
DESCRIPTION
The
μ
PC8112TB is a silicon monolithic integrated circuit designed as 1st frequency downconverter for
cellular/cordless telephone receiver stage. This IC consists of mixer and local amplifier. The
μ
PC8112TB features
high impedance output of open collector. Similar ICs of the
μ
PC2757TB and
μ
PC2758TB feature low impedance
output of emitter follower. These TB suffix ICs which are smaller package than conventional T suffix ICs contribute to
reduce your system size.
The
μ
PC8112TB 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.
