SST12LF03-Q3DE

PR OP R CO IE NF TAR ID Y E N AN TIA D L 2.4 GHz High-Gain, High-Efficiency Front-end Module SST12LF03 A Microchip Technology Company Data Sheet 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. Features • Input/output ports are matched to 50 internally and DC decoupled. • Temperature and load insensitive on-chip power detector – >20 dB dynamic range, temperature-stable, on-chip power detection • Packages available – 20-contact UQFN – 3mm x 3mm x 0.55mm • All non-Pb (lead-free) devices are RoHS compliant Receiver Chain: • LNA ON: Transmitter Chain: – Typically 12 dB gain – 3.1 dB noise figure – >5dB P1dB • 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 Bluetooth Path: • Typically 2.5 dB loss • Simultaneous BT/WLAN Rx mode: – 8 dB gain – 3.1 dB noise figure – ~25% @ POUT = 22 dBm for 802.11b/g Applications • Low IREF power-up/down control – IREF
