The PC8130TA and PC8131TA are silicon monolithic integrated circuits designed as variable gain amplifier. Due to 800 MHz to 1.5 GHz operation, these ICs are suitable for RF transmitter AGC stage of digital cellular telephone. These ICs are lower distortion than conventional PC8119T and PC8120T so that 15 dBm input level can be applied. These ICs also available in two types of gain control so you can choose either IC in accordance with your system design. 3 V supply voltage and minimold package contribute to make your system lower voltage, decreased space and fewer components. The PC8130TA and PC8131TA are 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.
