Highly integrated RF front-end module for 802.11n Wi-Fi products
( 01 Feb 2008 )
SiGe Semiconductor has launched what it says is 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 and 5GHz 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 SE2593A features the highest transmit power levels in the market, including +19dBm in 2.5GHz and +16dBm at 5GHz, at best-in-class ACPR performance. The device includes an integrated power detector with 20dB 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.
