The SST12LF03 is a fully integrated Front-End Module (FEM) for WLAN 802.11b/g/n and Bluetooth? systems. The SST12LF03 RF modules includes a PA, a LNA,and an antenna switch, making it ideal for WLAN/BT embedded applications where small size and high performance are required. Designed in compliance with IEEE 802.11 b/g/n applications and based on GaAs PHEMT/HBT technology, the SST12LF03 operates within the frequency range of 2.4- 2.5 GHz with a very low DC-current consumption. The Transmitter chain has excellent linearity, typically 3% added EVM up to 19 dBm output power for 54 Mbps 802.11g operation, while meeting 802.11b spectrum mask at 22 dBm. The receiver chain provides a low noise amplifier and has options for simultaneous WLAN and Bluetooth operation.The SST12LF03 is offered in a 20-contact UQFN package.

   High gain:– Typically 28 dB gain across 2.4–2.5 GHz over temperature-20°C to +85°C for Transmitter.

   High linear output power:– Meets 802.11g OFDM ACPR requirement up to 21 dBm– 3% added EVM up to 19 dBm for 54 Mbps 802.11g signal– Meets 802.11b ACPR requirement up to 22 dBm

   High power-added efficiency/Low operating current for 802.11b/g/n applications– ~25% @ POUT = 22 dBm for 802.11b/gReceiver Chain:
