SA2411

+20 dBm single chip linear amplifier for WLAN

2003 Feb 07

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
