SST develops dual power amplifier for MIMO WLAN applications

SST Communications recently announced the industry’s first dual power amplifier for multiple-in-multiple-out (MIMO) WLAN systems. The SST12LP30 utilizes the 2.4 GHz band, and is designed for wireless 2×2 (two transmitters and two receivers) architectures. According to SST, their new amplifier uses two parallel channels, offering superior performance through channel matching, and at a reduced cost. They’ve also addressed the issue of signal fidelity and quality by placing 20dB of isolation between the two channels.

Frank Chang, vice-chairman and chief technical advisor at SST Communications, said, “Our dual power amplifier is the first to help wireless system designers maximize the throughput and range of their MIMO products without a significant impact on design costs. As the industry moves closer to the 802.11n standard, we will continue to enable our customers to capitalize on this growing market by delivering cutting-edge power solutions for the 2.4 and 5 GHz bands.”

The SST12LP30 uses up to 50% less PCB space than designs that use separate power amplifiers, and are said to be 25% more power-efficient. It can also be configured for cellular and handheld applications. Prices start at $0.65 per unit, when purchased in 10K unit quantities.
