SiGe Semiconductor announces a power amplifier, switch, and RF front-end reference design made to improve performance of Wi-Fi systems. The SE2528L power amplifier delivers output power of up to +23dBm at 3.0% error vector magnitude (EVM) while operating in 802.11g mode. When paired with the SE2560L DPDT RF switch, which features low insertion losses and high linearity, manufacturers can design systems that achieve output power of +20dBm at the antenna. The high output power allows users to maintain wireless connections over long distances when using access points, printers, desktop computers and other Wi-Fi-equipped consumer devices. The devices are combined in a complete RF front-end reference design that includes all of the circuitry required between the transceiver and the antenna, including the power amplifier, enable circuitry, power detector, switch, and filtering.
