The PC3210TB is a silicon monolithic integrated circuits designed as wideband amplifier. The PC3210TB is suitable to systems required wideband operation from HF to L band. This IC is manufactured using NEC's 20 GHz fT NESATTMIII 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.
