Atmel announces a PA for the WLAN market. The 2.4 GHz PA ATR7032 meets the 802.11b/g standard and is manufactured using Silicon Germanium (SiGe) technology. SiGe enables operation at a low supply voltage range (2.7 to 3.6 V), making the device suited to battery-driven applications such as PDAs, smart phones and notebook computers. Further applications include WLAN client cards for PCs and access points. The ATR7032 offers the following performance: 32 dB gain, a linear power output of 23 dBm at 11 Mb/s CCK, and a low Error Vector Magnitude (EVM) of 1.4% at an output power of 19 dBm under 54 Mbit/s OFDM conditions. This is done while keeping current consumption under 160 mA. The P1dB compression point is at 27 dBm. The PA includes an on-chip temperature-compensated power detector with a dynamic range of 20 dB, and standby/bias control logic that provides shut down and power-saving options. The PA includes fully on-chip input and interstage matching.
