A Microchip Technology Company
The SST12LF01 is a 2.4 GHz Front-End Module (FEM) that combines a high-per-
formance Low-Noise Amplifier (LNA) and a Power Amplifier (PA). Designed in
compliance with IEEE 802.11 b/g/n applications and based on GaAs PHEMT/HBT
technology, the SST12LF01 operates within the frequency range of 2.4- 2.55 GHz
at a very low DC-current consumption. The Transmitter chain has excellent linear-
ity, typically <3% added EVM up to 19 dBm output power, which is essential for 54
Mbps 802.11g operation while meeting 802.11g spectrum mask at 23 dBm. The
SST12LF01 is offered in a 24-contact WQFN package.
Features
• Gain:
– Typically 12 dB gain across 2.4–2.5 GHz for Receiver
(RX) chain.
– Typically 29 dB gain across 2.4–2.5 GHz over temperature
0°C to +80°C for Transmitter (TX) chain.

– ~3% added EVM up to 19 dBm for
54 Mbps 802.11g signal
– Meets 802.11b ACPR requirement up to 24 dBm
• High power-added efficiency/Low operating cur-
rent for both 802.11g/b applications
– ~22%/210 mA @ P
= 22 dBm for 802.11g
OUT
– ~26%/240 mA @ P
= 23.5 dBm for 802.11b
