802.11 b/g Power Amplifier

( 1 Oct 2006 )

Avago Technologies' E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) power amplifier is designed for IEEE 802.11b/g mobile wireless local area networks (WLANs). The MGA-412P8 features high linear output power at a low operating current with a shutdown function to conserve battery power, and is supplied in a 2 x 2mm LPCC (leadless plastic chip carrier) package. The device is suitable for portable WLAN applications such as PDAs and mobile handsets, digital cameras, printers and print servers. It is also appropriate for use as a power amplifier for RFID transmitters, luetooth and other applications in the license-free 2.4GHz ISM (industrial, scientific and medical) band. At 2.452GHz and 3.3V bias, the MGA-412P8 provides 25.5dB gain as well as +19dBm linear power output with IEEE 802.11g OFDM (orthogonal frequency division multiplexing) modulation at a 54Mbps data rate, and three percent EVM (error vector magnitude) while consuming only 95mA current.
