DESCRIPTION
The µPC1679G is a silicon monolithic integrated circuit designed as medium output power amplifier for high frequency system applications. Due to +13 dBm TYP. output at 1 GHz, this IC is recommendable for transmitter stage amplifier of L Band wireless communication systems. This IC is packaged in 8-pin plastic SOP. This IC is manufactured using NEC’s 20 GHz fT NESAT™ IV 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.
