Manufacturing Technology

The PE43704MLCA-Z is made using pSemi’s state-of-the-art UltraCMOS® method, which is a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. This unique way of making things combines the performance benefits of GaAs with the cost benefits and integration powers of regular CMOS. This makes sure that both performance and cost-effectiveness are at their best.

Manufacturing Technology

The PE43704MLCA-Z is made using pSemi’s cutting-edge UltraCMOS® method, which is a patented variation of silicon-on-insulator (SOI) technology built on a sapphire substrate. This new way of making things blends the best parts of Gallium Arsenide (GaAs) technology with the advantages of CMOS technology in terms of cost and integration.

Using silicon-on-insulator technology has a number of positive effects. The sapphire substrate has good electrical isolation, which cuts down on parasitic capacitance and leakage currents that aren’t needed. This means that the RF performance is better and less power is used. Also, the UltraCMOS method makes it possible to put both active and passive parts on a single chip. This makes the chip work better overall and reduces the need for extra parts.

The PE43704MLCA-Z has great RF performance because it takes advantage of GaAs technology. GaAs is known for having high electron mobility, which lets it switch quickly and have low noise. This means that the reduction will work more linearly and with less distortion.

Integration of traditional CMOS technology also has economic benefits, such as low-cost manufacturing methods and the ability to make a lot of products at once. It makes it possible for the PE43704MLCA-Z to be made at a price that is competitive without sacrificing efficiency or reliability.

In short, pSemi’s UltraCMOS technology, which is built on a sapphire substrate, blends the performance benefits of GaAs with the cost benefits and ease of integration of traditional CMOS. This unique way of making the PE43704MLCA-Z makes sure that it has high-quality RF performance, uses power efficiently, and is a cost-effective answer for a wide range of RF applications.
