2.4GHzHigh-Gain,High-EfficiencyFront-endModule SST12LF03 A Microchip Technology Company Product Brief SST12LF03 is a fully integrated Front-End Module (FEM) for WLAN 802.11b/g/n and Blue- tooth systems. SST12LF03 RF module includes a PA, a LNA, and an antenna switch, making it ideal for WLAN/BT embedded applications where small size and high perfor- mance are required. Based on GaAs PHEMT/HBT technology, 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. Bluetooth Path: Features Typically 2.5 dB loss Input/output ports are matched to 50 internally and DC decoupled. Simultaneous BT/WLAN Rx mode: 8 dB gain Packages available 3.1 dB noise figure 20-contact UQFN 3mm x 3mm x 0.55mm All non-Pb (lead-free) devices are RoHS compliant Applications WLAN (IEEE 802.11b/g/n) Transmitter Chain: Home RF High gain: Typically 28 dB gain across 2.42.5 GHz over tempera- Cordless phones ture -20C to +85C for Transmitter. 2.4 GHz ISM wireless equipment High linear output power (at 3.3V): Meets 802.11g OFDM ACPR requirement up to 21 dBm Zigbee 3% added EVM up to 19 dBm for 54 Mbps 802.11g signal Meets 802.11b ACPR requirement up to 22 dBm Bluetooth High power-added efficiency/Low operating cur- rent for 802.11b/g/n applications ~25% P = 22 dBm for 802.11b/g Block Diagram OUT Low shut-down current (~2 A) V PA V DET EN CC Limited variation over temperature ~1 dB power variation between -20C to +85C ~2 dB gain variation between -20C to +85C CRX TX IN Temperature and load insensitive on-chip power detector >20 dB dynamic range, temperature-stable, on-chip power detection CTX WLAN RX Antenna OUT Receiver Chain: LNA ON: BT Typically 12 dB gain 3.1 dB noise figure >5dB P1dB CBT CBTR V DD 12LF03-BlockDiagram 2012 Silicon Storage Technology, Inc. www.microchip.com DS75028A 01/122.4GHzHigh-Gain,High-EfficiencyFront-endModule SST12LF03 A Microchip Technology Company Product Brief Product Ordering Valid combinations for SST12LF03 SST12LF03-Q3DE SST12LF03 Evaluation Kits SST12LF03-Q3DE-K Note: Valid combinations are those products in mass production or will be in mass production.
