MGA-412P8
GaAs Enhancement-mode pHEMT Power Amplifier
optimized for IEEE 802.11b/g applications
Data Sheet
Description
Avago Technologies’s MGA-412P8 linear power
amplifier is designed for applications in the (1.7-3)
GHz frequency range. The amplifier is optimized for
IEEE 802.11b/g WLAN applications and has a best-in-
class efficiency (PAE) of 25.5% (54Mbps OFDM)
achieved through the use of Avago Technologies’
proprietary GaAs Enhancement-mode pHEMT
process.
The MGA-412P8 is housed in a miniature 2.0 x 2.0 x
0.75mm
3
8-lead leadless-plastic-chip-carrier (LPCC)
package. The compact footprint, low profile and
excellent thermal efficiency of the LPCC package
makes the MGA-412P8 an ideal choice as a power
amplifier for mobile IEEE 802.11b/g WLAN
applications.
It achieves +19.0 dBm linear output power that meets
3% EVM at 54Mbps data rate (OFDM Modulation),
and 23dBm at 11Mbps (CCCK modulation).
