2.4 GHz High-Gain, High-Efficiency Front-end Module

SST12LF02

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

mance Power Amplifier (PA) and a switch within a compact, fully-matched package.

Designed in compliance with IEEE 802.11b/g/n applications and based on GaAs

PHEMT/HBT technology, the SST12LF02 operates within the frequency range of 2.4-

2.5 GHz with very low DC-current consumption. The Transmitter chain has excellent

linearity, typically <3% added EVM up to 18 dBm output power, with 802.11g 54 Mbps

OFDM operation while meeting 802.11b/g/n spectrum mask at 21 dBm. An option to

simultaneously connect the WLAN and Bluetooth receiver ports is available. The

SST12LF02 is offered in a 16-contact XQFN package.
