Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced its latest 2.4 GHz, 50 ohm Matched RF WLAN Front End Module (FEM)—the SST12LF09—for Bluetooth ® connectivity, as well as 802.11b/g/n and 256-QAM Wi-Fi ® applications. The SST12LF09 integrates a transmitter power amplifier, a receiver low-noise amplifier, and a low-loss, single-pole three-throw antenna switch for Bluetooth connectivity into one compact 2.5x2.5x0.4 mm, 16-pin QFN package, making it ideal for high-data-rate wireless applications. With its high linear output power of up to 15 and 17 dBm for 1.8% dynamic EVM at 3.3V and 5V, respectively—along with 17 and 18.5 dBm linear power for 3% EVM at 3.3V and 5V, respectively—this FEM significantly extends the range of IEEE 802.11b/g/n WLAN systems while providing excellent transmit power at the maximum 256-QAM data rate. The receiver has a 12 dB gain and a greater than -6 dBm input (1 dB) compression level. In the LNA bypass mode, the receiver has a 9 dB loss and an 8 dBm input compression level.
Attaining the maximum data rate, longest range and highest integration in a small package is essential to the designers of mobile devices, multi-channel access point/routers and set-top boxes. Developers can take advantage of the SST12LF09’s small package size and extra output power at 5V bias to reduce the board size and complexity of their designs while boosting their products’ output power. This FEM also features 50 ohm on-chip input and output match, which is easy to use and shortens time to market.
“Microchip’s 2.4 GHz 256-QAM power amplifiers are generating a high level of interest within the WLAN market, due to their high linear power and efficiency,” said Daniel Chow, vice president of Microchip’s RF Division. “With the release of the SST12LF09, Microchip is building on that reputation with a compact, 256-QAM front end module that offers the same reliable, high-efficiency operation and low dynamic EVM over temperature, while adding a low-noise receiver, which combine to extend the range of 2.4 GHz ultra high data rate mobile devices, routers and set-top boxes.”
