SILICON MMIC LOW CURRENT AMPLIFIERS
FOR CELLULAR/CORDLESS TELEPHONES
DESCRIPTION
The
µ
PC8128TA,
µ
PC8151TA and
µ
PC8152TA 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
Ω
wideband matched IC. These low current
amplifiers operate on 3.0 V.
These ICs are manufactured using NEC’s 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, these ICs have excellent performance, uniformity and reliability.

These ICs can be added to your system around
V
parts, when you need more isolation or gain. The application
herein, however, shows only examples, therefore the application can depend on your kit evaluation.
