AFEM-S105
5 GHz WiFi FEM
Data Sheet
Description
Avago Technologies AFEM-S105 WiFi FEM includes power
amplifier, directional coupler, and SPDT antenna switch.
It is designed for mobile and fixed wireless data applica-
tions in the 5.15 to 5.85 GHz frequency ranges. The PA is
optimized for IEEE 802.11 a/n WiFi modulation. 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 AFEM-S105 is packaged in a 3.2 x 3.2 x 0.6 mm size for
space-constrained applications.
