SST12LF02中文资料2.4 GHz High-Gain, High-Efficiency Front-end Module数据手册Microchip规格书

描述 Description

The SST12LF02 is a 2.4 GHz Front-end Module (FEM)designed in compliance with IEEE 802.11b/g/n applications.It combines a high-performance Power Amplifier (PA)and a switch. There are three components to the FEM: theReceiver (RX) chain, the Transmitter (TX) chain, and theBluetooth® (BT) chain.The TX chain includes a high-efficiency PA based on theInGaP/GaAs HBT technology. This chain typically provides29 dB gain with 30% power-added efficiency (PAE) @POUT = 22 dBm for 802.11g and 29% PAE@POUT = 22dBm for 802.11bThe TX chain has excellent linearity, typically ~2.5% addedEVM at 18 dBm output power which is essential for 54Mbps 802.11g operation while meeting 802.11g spectrummask at 22 dBm.The SST12LF02 also features easy board-level usagealong with high-speed power-up/down controls. Ultra-lowreference current (total IREF ~2 mA) makes the SST12LF02controllable by an on/off switching signal directly from thebaseband chip. These features, coupled with low operatingcurrent, make the SST12LF02 ideal for the final stagepower amplification in battery-powered 802.11b/g/n WLANtransmitter applications.
