Silicon-Based 802.11bgn WLAN Power Amplifier
SiGe Semiconductor, Inc.'s SE2576L is a 2.4 GHz Wireless LAN power amplifier (PA) module. The new IEEE 802.11bgn device is the industry's smallest and most efficient power amplifier operating at 26 dBm. The SE2576L targets applications requiring high RF transmit power such as residential video and data transport, enterprise and outdoor networks as well as public hotspots, delivering complete area coverage and improved link budgets for more effective broadband data services. The device is fabricated in silicon germanium, a technology nearly identical to standard silicon and three times more thermally conductive than GaAs. The SE2576L integrates the input match and the external output match to adjust the load line for 5V, 26 dBm operation enabling simplified design, quicker time to market and higher production yield for users. The SE 2576 features a temperature compensated, load insensitive power detector with 20dB of dynamic range and <1.2dB variation under 3:1 mismatch at the antenna. The combination of this power detector and the inherent thermal dissipation benefits of silicon germanium equips the SE2576L to deliver consistent performance over temperature extremes in high power applications where self-heating requires special attention.
