MGA-22103
2.5-2.7 GHz WiMAX Power Amplifier Module
Data Sheet
Description
Avago Technologies MGA-22103 power amplifier module
is designed for mobile and fixed wireless data applications
in the 2.5 to 2.7 GHz frequency range. The aggressive gain
shape limits the noise injected into radio receivers co-
located in the same device. The PA is optimized for IEEE
802.16 WiMAX modulation but can be used for any high
linearity applications. The PA exhibits flat gain and good
match while providing linear power efficiency to meet
stringent mask conditions. It utilizes Avago Technologies
proprietary GaAs Enhancement-mode pHEMT technology
for superior performance across voltage and temperature
levels.
The MGA-22103 is packaged in a 3 x 3 x 1 mm package for
space-constrained applications.
