Product data
SA2411
1. DESCRIPTION
The SA2411 is a linear power amplifier designed for WLAN application in the 2.4 GHz band. Together with the SA2400A the chips form a
complete 802.11b transceiver. The SA2411 is a Si power amplifier with integrated matching and power level detector.
2. FEATURES
• 75 Ω + 25j Ω differential inputs, internally matched
• 50 Ω single-ended output, internally matched
• 15 dB gain block
• Power detector
• Bias adjust pin
• 18% efficiency at 3 V
• RF matching for SA2400A
3. APPLICATIONS
• IEEE 802.11 and 802.11b radios
• Supports DSSS and CCK modulation
• Supports data rates: 1, 2, 5.5, and 11 Mbps
• 2.45 GHz ISM band wireless communication devices
