DESCRIPTION

The μPC8128TB, μPC8151TB and μPC8152TB are silicon monolithic integrated circuits designed as buffer amplifiers for cellular or cordless telephones. These amplifiers can realize low current consumption with external chip inductor (eg 1005 size) which can not be realized on internal 50 ? wideband matched IC. These low current amplifiers operate on 3.0 V.

These ICs are manufactured using NEC’s 20 GHz fT 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, these ICs have excellent performance, uniformity and reliability.
