Highly-integrated dual-band front-end module for WLAN and WiMAX applications based on LTCC technology

A very compact dual-band LTCC module supporting WiMAX IEEE 802.16e-2005 and Wi-Fi IEEE 802.11a/b/g standards is presented. The frontend module (FEM) integrates in less than 50mm
²
all required passive and active functions for 1×2 (1 Transmit, 2 receive paths) MIMO operability. The FEM package has SMT compatible footprint and is 1.4mm high. Full FEM measurements results show good performance and fully validate the passive integration approach.
