MAX2247 Datasheet | Maxim Integrated

19-2520; Rev 4; 8/03 2.4GHz SiGe Linear Power Amplifier General Description The MAX2247 low-voltage, three-stage linear power amplifier (PA) is optimized for 802.11b/g wireless LAN (WLAN) applications in the 2.4GHz ISM band. The device is integrated with an adjustable bias control, power detector, and shutdown mode. The MAX2247 Features 29dB of power gain and delivers up to +24dBm of linear output power at 24% efficiency from a single +3.3V supply. It achieves less than -32dBc firstside lobe suppression and less than -55dBc secondside lobe suppression under 802.11b modulation. In addition, the device can be matched for optimum efficiency and performance at output power levels from +10dBm...
