2.4 GHz WLAN High-Gain, High-Efficiency FEM

SST12LF02

SST12LF02 is a 2.4 GHz Front-End Module (FEM) that combines a high-perfor-

mance Power Amplifier (PA) and a single-pole, three-throw, antenna switch for Tx/

QAM applications and based on GaAs PHEMT/HBT technology, the SST12LF02

operates within the frequency range of 2.4- 2.5 GHz at a very low DC-current con-

sumption. The Transmitter chain has excellent linearity, typically 3% EVM up to 18

dBm output power, for 54 Mbps 802.11g operation while meeting 802.11g spec-

trum mask at 21 dBm. The transmitter will also provide 17 dBm with 11n, MCS7-

HT40 modulation and 16 dBm with 256 QAM MCS9-HT40 modulation.

SST12LF02 is offered in a 16-contact XQFN package.
