Highly-integrated power amplifier for WLAN

18 May 2005 Analogue, Mixed Signal, LSI

Atmel's new WLAN power amplifier (PA) for the fast-growing high-volume WLAN market meets the 802.11b/g standard and is manufactured using Atmel's advanced Silicon Germanium (SiGe) technology.

The SiGe process allows the 2,4 GHz ATR7032 device to operate at a low supply voltage range (2,7 to 3,6 V), making it particularly suited to battery-driven applications. The ATR7032 offers superior performance: 32 dB gain, a linear power output of 23 dBm at 11 Mbps CCK, and an extremely low error vector magnitude (EVM) of 1,4% at an output power of 19 dBm under 54 Mbps OFDM conditions. This is done while keeping current consumption under 160 mA. The P1dB compression point is at 27 dBm. This means that the system designer will achieve a high data transmission range at a relatively low current consumption, says Atmel.
