DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
PC8112TB
DESCRIPTION
The
PC8112TB 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. The
PC8112TB features
high impedance output of open collector. Similar ICs of the
PC2757TB and
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
PC8112TB is manufactured using the 20 GHz f
T
NESAT™III 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.
