The PC2756TB is a silicon monolithic integrated circuit designed as L band frequency downconverter for receiver stage of wireless systems. The IC consists of mixer and local oscillator. The TB suffix IC which is smaller package than conventional T suffix IC contributes to reduce your system size. The PC2756TB is manufactured using NEC's 20GHz 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.
