3 V, SUPER MINIMOLD SILICON MMIC
WIDEBAND AMPLIFIER FOR MOBILE COMMUNICATIONS
BIPOLAR ANALOG INTEGRATED CIRCUIT
DESCRIPTION
The
PC2745TB and
PC2746TB are silicon monolithic integrated circuits designed as buffer amplifier for mobile
communications. These low current amplifiers operate on 3.0 V (1.8 V MIN.).
These ICs are manufactured using our 20 GHz f
T
NESATIII 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, these IC have excellent performance, uniformity and reliability.
