Abstract :
A fully integrated ultra-linear high power front-end module (FEM) for 802.11b/g wireless local area network (WLAN) applications is presented. Unlike traditional 2.4 GHz 802.11b/g RF front-ends, the FEM operates from 2.3 GHz to 2.5 GHz, encompassing Korean WLAN applications. For 802.11g 54 Mbps applications, the module can deliver >21 dBm and >24 dBm with an error vector magnitude (EVM) <-28 dB for 3.3 volt and 5 volt applications, respectively. For 802.11b 11 Mbps applications, the FEM can deliver >25 dBm and >28 dBm for 3.3 volt and 5 volt applications, respectively. Design methodologies, the layout parameterization method (Huang, C.P. et al., IEEE RFIC Symp. Dig., p.587-90, 2003) and the non-linear behavioral modeling technique (Shihab Kuran et al., IEEE ICECS Symp. Dig., 2003), are also presented.
