MGA-22003
2.3-2.7 GHz 3x3mm WiMAX and WiFi Power Amplier
Preliminary Data Sheet
Description
Avago Technologies MGA-22003 linear power amplier is
designed for mobile and xed wireless data applications
in the 2.3 to 2.7 GHz frequency range. The PA is optimized
for IEEE 802.16 WiMAX modulation but can be used for
any high linearity applications. The PA exhibits at gain
and good match while providing linear power eciency
to meet stringent mask conditions. It utilizes Avago Tech-
nologies proprietary GaAs Enhancement-mode pHEMT
technology for superior performance across voltage and
temperature levels.
The MGA-22003 is packaged in a 3x3x1 mm package for
space-constrained applications.
Applications
• Portable WiMAX and WiFi applications
• WiMAX and WiFi Access points

Recommended turn on sequence
• Apply VCC1 and VCC2 3.3V
• Apply BSPLY 3.3V
• Apply BCTRL 2.8V
• Apply BSW 1.8V
• For HPM Apply PAMOD 1.8V for LPM Apply PAMOD 0V
• Apply RF In not to exceed 10dBm
Typical Test Conditions:
HPM LPM
VCC1,2 3.3V 3.3V Supply Voltage
PAMOD 1.8V 0V Low Power Mode
B_SPLY 3.3V 3.3V Bias Voltage
B_CTRL 2.8V 2.8V Bias Control
B_SW 1.8V 1.8V PA Enable
Note2: VCC1, VCC2 and B_SPLY can be tied together to reduce supply
voltages, but B_CTRL needs to be a regulated voltage which is optimized
for 2.8V.
