DESCRIPTION
μ
PC2745T and
μ
PC2749T are silicon monolithic integrated circuits designed as buffer amplifiers for mobile
communications. These ICs feature 3V bias supply and 2.7 or 2.9 GHz wide band operation. 3 V supply
operation is suitable for low voltage systems. 2.7 GHz or 2.9 GHz wide band operation is applicable for not
only celular/cordless telephones but also wireless LAN and so on. Due to the 50
cascadable and mini-mold
package, these ICs are suitable for high-density surface mounting.
These ICs are manufactured using NEC’s 20 GHz f
T
NESAT
TM
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 series have exellent performance, uniformity and
reliability.
