DESCRIPTION

The

PPC8128TA, PPC8151TA and PPC8152TA are silicon monolithic integrated circuits designed as buffer

amplifiers for cellular / cordless telephones. These amplifiers can realize low current consumption with external chip

inductor (example: 1005 size) which can not be realized on internal 50

: wideband matched IC. These low current

amplifiers operate on 3.0 V.

silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution

and prevent corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability.
