AFEM-S105-BLKG

P1-P3P4-P6P7-P9P10-P11
AFEM-S105
5 GHz WiFi FEM
Data Sheet
Description
Avago Technologies AFEM-S105 WiFi FEM includes power
ampli er, directional coupler, and SPDT antenna switch.
It is designed for mobile and  xed 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  at gain and good match while providing linear
power e ciency 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.

Electrical Speci cations
All data measured on an Avago demo board at Vdd = 3.3 V, Tc = 25° C, 50 at all ports. Unless otherwise speci ed, all
data is taken at 54 Mbps 64QAM modulated signal per IEEE 802.11a with 20 MHz BW at 5.15 – 5.85 GHz. For TX mode
PAEN = SW1 = 2.9 V, SW0 = 0 V. For RX mode SW0 = 2.9 V, PAEN = SW1 = 0 V.
