MAX2247 - 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.

Key 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 to +24dBm. Its high +28dBm saturated output power also allows the device to meet the requirements of 802.11g OFDM modulation. The MAX2247 feat.
