MGA-23003
3.3-3.8 GHz WiMAX Power Amplifier (3x3mm)
Data Sheet
Description
Avago Technologies MGA-23003 linear power amplifier is
designed for mobile and fixed wireless data applications
in the 3.3 to 3.8 GHz frequency ranges. 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 Tech-
nologies proprietary GaAs Enhancement-mode pHEMT
technology for superior performance across voltage and
temperature levels.
The MGA-23003 is packaged in a 3x3x1 mm size for space-
constrained applications.

All data measured on an FR4 demo board at Vcc1 = Vcc2 = 3.3V, BCTRL = 2.8V, Tc = 25°C, 50
at all ports. Unless
otherwise specified, all data is taken with OFDM 16-QAM modulated signal per IEEE 802.16e with 10MHz BW operating
over the BW of 3.3GHz to 3.8GHz.
