The PC2726T is a silicon microwave monolithic integrated circuit designed for miniature differenctial amplifier. This IC operates up to 1.6 GHz and therefore is suitable for BS tuner, mobile communication and measurement equipment applications. This IC can also use as differential oscillator application. The PC27xx series is manufactured using NEC's 20 GHz fT NESATTM III silicon bipolar process. This process uses silicon nitride passivation film and gold metallization wirings. external pollution and prevent corrosion and migration.
