2.4 GHz High-Gain, High-Efficiency Front-end Module
A Microchip Technology Company
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.
Product Brief
Features
• High Gain:
– Typically 29 dB gain across 2.4–2.5 GHz over tempera-
ture -20°C to +85°C for Transmitter (TX) chain.
• High linear output power (at 3.3V):
– Meets 802.11g OFDM ACPR requirement up to 21 dBm
– <3% added EVM up to 18 dBm for
54 Mbps 802.11g signal
– Meets 802.11b ACPR requirement up to 21 dBm
