SiGe Semiconductor's Power Amplifiers Boost Wi-Fi Systems

(Product News, 16 Apr 2008)

SiGe Semiconductor Inc. has launched a new power amplifier designed to optimize performance of Wi-Fi systems including access points, personal computers and PC cards. The SE2587L power amplifier, based on SiGe Semiconductor's proven high-performance architecture, delivers excellent linearity at industry leading transmit power levels of +19dBm in 802.11g mode and +24dBm in 802.11b mode. The high linearity optimizes transmission of greater data rates over longer distances, thereby allowing systems to support emerging wireless multimedia applications such as video distribution, video streaming and high-speed data.

The SE2587L is the smallest of SiGe Semiconductor's discrete power amplifiers, packaged in a 3x3 QFN package. The device pin-out sequence is compatible with the company's SE2527L, SE2528L and SE2581L, minimizing the layout changes and allowing manufacturers to easily migrate to the new device for next-generation designs. To further reduce system cost, SiGe Semiconductor offers application notes and support to replace discrete inductors used for output matching to patterned-on traces, taking advantage of the board space freed by the smaller footprint of the SE2587L. This could result in a savings of about 20 percent off the external bill of materials.
