PC8112TB
SILICON MMIC 1st FREQUENCY DOWN-CONVERTER
FOR CELLULAR/CORDLESS TELEPHONE
DESCRIPTION
The
碌
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
碌
PC8112TB features
high impedance output of open collector. Similar ICs of the
碌
PC2757TB and
碌
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
碌
PC8112TB is manufactured using NEC鈥檚 20 GHz f
T
NESAT鈩II 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.
