Abstract

This work presents ultra small frontend modules (FEMs) for wireless-LAN. Based on LTCC technology, two different fully-integrated FEMs have been built. The first one is a 2.4 GHz FEM for 802.11 b/g. The second is a fully-featured dual-band (2.4 and 5 GHz) FEM for 802.11 a/b/g. The measurements demonstrate superior performance of the modules compared to current discrete solutions. According to the authors´ knowledge, the new FEMs are the highest-integrated and smallest-size WLAN frontend circuits reported so far.
