The PC2776TB is a silicon monolithic integrated circuits designed as wideband amplifier. This amplifier has impedance near 50 in HF band, so this IC suits to the system of HF to L band. This IC is manufactured using NEC's 20 GHz fT NESATTM 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 IC has excellent performance, uniformity and reliability.
