New SiGe Chips Boost Speeds In Emerging Wireless & IoT Devices

GLOBALFOUNDRIES launched new advanced Silicon Germanium (SiGe) power amplifier (PA) products designed for cellular and Wi-Fi front-end modules in mobile devices, access points, Internet of Things, and more.

The newest offerings, 5PAx and 1K5PAx, are optimized to meet the rigorous demands of evolving mobile standards like 802.11ac, which demands three times faster data throughput than the previous standards. With improved power efficiency, noise figure and insertion loss, the devices enable more power efficient next-generation Wi-Fi and cellular solutions for faster data access and uninterrupted connections.

“Mobile suppliers are facing mounting pressure to expand network capacity as wireless data consumption continues to increase rapidly,” said Dr. Bami Bastani, senior vice president of GLOBALFOUNDRIES RF business unit. “Our broad portfolio of high-performance SiGe power amplifier technologies provides a distinct design, performance and cost advantage that enables our mobility customers to deliver cost-effective solutions with faster data throughput, support wider coverage areas, and consume less power.”

The SiGe PA devices comprise four technologies: SiGe 5PAe, 1KW5PAe, 5PAx and 1K5PAx. The devices feature through-silicon via technology for significant performance, integration functionality and cost advantages for customers who are currently using gallium arsenide (GaAs)-based alternatives. In addition, size is minimised by implementing multiple RF functions on a chip addressing the needs for portable wireless communication devices.

For 5GHz applications, the SiGe 5PAx supports 2dB gain along with a 5 percent PAE and 0.2dB low noise amplifier (LNA) improvements. The new SiGe 1K5PAx enables designers to minimize form factor by implementing multiple functions, such as power amplifiers, RF switches and LNAs, on a single chip.
