Just fresh into my email in-box this morning: The Microchip SST12LF09 RF front-end helps system=20 designers to extend the transmission range for=20 high-data-rate wireless applications such as=20 mobile devices, multi-channel access points or=20 routers and set-top boxes while minimising the board space. Integrated into the SST12LF09 2.4 GHz RF=20 front-end module's compact 2.5 x 2.5 x 0.4 mm=20 package is a transmitter power amplifier, a=20 receiver low-noise amplifier and a low-loss,=20 single-pole three-throw antenna switch for=20 Bluetooth=AE connectivity as well as 50 Ohm matched=20 input/output ports. This high level of=20 integration enables the SST12LF09 to deliver high=20 linear output power and gain for IEEE=20 802.11b/g/n/ac Wi-Fi=AE up to the maximum 256-QAM data rate. The small package size and up to 5V operating=20 voltage range reduce board space and design=20 complexity whilst providing the flexibility to=20 boost output power with the 5V bias. At 3.6V,=20 linear output power of up to 15 dBm provides 1.8%=20 dynamic EVM, or 3% EVM with a linear output of 17=20 dBm. At 5V, the linear output power is increased=20 to 16.5 dBm with 1.8% dynamic EVM or 18.5 dBm with 3% EVM. Find out more and order samples at: www.microchip.com/get/eusst12lf09 Note that +17dBm is 50mW - quite decent. dwayne At 11:26 AM 2/11/2014, veegee wrote: >Hate to bump, but does anyone have any idea if I'm going in the right >direction with this?
