MGA-25203
5.1 - 5.9 GHz WiFi and WiMAX Power Amplifier (3x3mm)
Data Sheet
Description
Avago Technologies MGA-25203 linear power amplifier is
designed for mobile and fixed wireless data applications
in the 5.1 to 5.9 GHz frequency ranges. The PA is optimized
for IEEE 802.11a/n WLAN and 802.16 WiMAX 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 Enhance-
ment-mode pHEMT technology for superior performance
across voltage and temperature levels.
The MGA-25203 is packaged in a 3x3x1 mm size for space-
constrained applications.

WLAN (802.11 a) Electrical Specifications
All data measured on an FR4 demo board at Vcc1 = Vcc2 = 3.3V, Tc = 25°C, 50
at all ports. Unless otherwise specified,
all data is taken at 54Mbps 64QAM modulated signal per IEEE 802.11a with 20MHz BW at 4.9 - 5.9GHz. This module is
intended for frequency band 5.1-5.9GHz. The following data from 4.9 to 5.1GHz shows that the PA is fully functional with
degraded performance.
