SiGe Delivers World’s Most Integrated RF Front-End Module for 802.11n Wi-Fi® Products
October, 2007—Ottawa, Ontario – October 9, 2007
SiGe Semiconductor, Inc. today announced the world’s most integrated RF front-end module for Wi-Fi® products designed to comply with the IEEE 802.11n specification. The SE2593A provides a complete 2.4 GHz and 5 GHz WLAN multiple input, multiple output (MIMO) RF solution including all of the circuitry required between the transceiver and the antennas. The device delivers optimal performance for supporting high-bandwidth wireless multimedia services while enhancing size, system-level cost and manufacturability.
The IEEE 802.11n specification is a fast growing segment of the Wi-Fi market. Products equipped with 802.11n feature enhanced range and throughput of wireless transmission while maintaining backwards compatibility to the enormous worldwide installed base of WLAN infrastructure. The higher throughput allows WLAN products to support traditional voice and data applications while also meeting increased consumer demand for streaming video applications.
“The new SE2593A provides the optimal solution to customers aiming to capitalize on the growing market for high-bandwidth wireless services,” said Jose Harrison, director product marketing, computer and consumer at SiGe Semiconductor. “Our new module is easy to implement, and provides integration, performance and flexibility that surpasses any other solution on the market. These benefits allow manufacturers to get their products to market quickly while also ensuring an optimal end-user experience.”
SiGe Semiconductor’s new SE2593A features 2.4GHz and 5GHz power amplifiers and low noise amplifiers, power detector, transmit and receive switch, diplexers and associated matching in a miniature land grid array package that measures just 5mm x 6mm x 1mm. The new front-end module replaces up to 20 components which would be required to implement a discrete 1x1 MIMO solution. The small size allows multiple modules to create 2 transmit by 2 receive (2x2), 3x3 or 4x4 MIMO designs in support of higher bandwidth for streaming video applications, while accommodating shrinking form factors.
The SE2593A is the smallest commercially available MIMO front-end to integrate a dual-band LNA. The integrated LNA improves total system noise figure, enhancing range and throughput to ensure better overall system performance. Eliminating the need for external LNAs also reduces system bill of material, and simplifies design, test and manufacture.
The SE2593A features the highest transmit power levels in the market, including +19 dBm in 2.5 GHz and +16 dBm at 5 GHz, at best-in-class ACPR performance. The device also includes an integrated power detector with 20 dB of dynamic range. The high performance optimizes transmission of higher data rates over longer distances, thereby allowing systems to support emerging 802.11n applications such as video distribution, video streaming and high-speed data.
All RF ports are matched to 50 ohms to simplify PCB layout and the interface to the transceiver RFIC. The module is fully tested for ease of design and optimal yields.
Availability and Price
The SE2593A is sampling to lead customers now. The device is shipping in volume now, priced at US $4.25 in 10k unit quantities.
