GLOBALFOUNDRIES has announced new advanced radio-frequency (RF) silicon solutions, further expanding their portfolio of Silicon Germanium (SiGe) power amplifier (PA) technologies designed to enable performance-optimized cellular and Wi-Fi solutions in increasingly sophisticated mobile devices and hardware.
The 5PAx and 1K5PAx, together called PAx, are the latest extensions to its broad family of SiGe-based PA technologies. The advanced offerings deliver optimized PA, LNA and switch technology with improved power efficiency, noise figure and insertion loss enabling more power efficient next-generation Wi-Fi and cellular solutions for faster data access and uninterrupted connections.
This broad portfolio of high-performance SiGe power amplifier technologies provides a distinct design, performance and cost advantage that enables their mobility customers to deliver cost-effective solutions with faster data throughput, support wider coverage areas, and consume less power.
Skyworks, a leader in high-performance analog semiconductor solutions, plans to use the technology to enhance both the power capability and efficiency for the next generation of mobile WLAN products and high-performance WLAN products, including access points, routers and IoT applications. With these advanced features and the ability to minimize form factor by implementing multiple RF functions on a chip, the latest PAx offerings enhance the capabilities of integrated semiconductor solutions that support customer needs for high performance, cost effective technologies addressing portable wireless communication devices.
There are four technologies in GLOBALFOUNDRIES' SiGe PA family, SiGe 5PAe, 1KW5PAe, and now 5PAx and 1K5PAx. All four offerings feature GLOBALFOUNDRIES' proven through-silicon via technology and provide significant performance, integration functionality and cost advantages for customers who are currently using gallium arsenide (GaAs)-based alternatives. Today, there are more than three billion SiGe power amplifiers shipped worldwide using this family of technologies, and GLOBALFOUNDRIES has recently invested in additional manufacturing capacity to address the anticipated growth in the mobile sector. 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 generation of standards.
For 5 GHz applications, SiGe 5PAx, the follow-on to SiGe 5PAe, supports 2 dB gain along with a 5 percent PAE and 0.2 dB low noise amplifier (LNA) improvements relative to the previous generation. SiGe 1K5PAx, like its predecessor 1KW5PAe, is built on a high-resistivity substrate, and is tuned for integration and higher performance. It features RF switches with approximately 15 percent better Ron-Coff compared to 1KW5PAe, and like 1KW5PAe, enables designers to minimize form factor by implementing multiple functions, such as power amplifiers, RF switches and LNAs, on a single chip.
