“…Inside the multilayer LTCC matching circuits, DC-and RF-routing as well as passive structures like filters, baluns and multiplexers are implemented [2][3][4][5][6][7]. LTCC has also been proven a viable platform for integration of power amplifiers and other active components with respect to thermal dissipation [8]. Besides purely RF active devices transceiver IC are also integrated to the LTCC module.…”

IntroductionThis paper presents a highly integrated WiMAX System-in-Package (SiP) based on LTCC technology (Low Temperature Co-fired Ceramics). It comprises the complete passive and active RF frontend plus the transceiver RFIC for up-and down-conversion to base band. The overall size of such a smart package strongly depends on the applied technology and level of integration (multiband/multimode). The benefits on size reduction coming from advanced integration and assembly technologies are discussed and a very compact LTCC SiP with less than 50 mm 2 size and SMT-compatible footprint is demonstrated. Top level measurements show full performance and thus fully validate the LTCC integration approach. Motivation

For high-data-rate multimedia access and measurement applications (such as channel sounding and radar) the 60 GHz unlicensed band is of interest for short range applications. Currently, there is enormous progress in the field of monolithic-millimeter-wave-integratedcircuits (MMIC) for 60 GHz technology, but there are still many challenges related to reliability and usable bandwidth for compact packaging solutions. The aim of this work is to demonstrate the implementation of miniaturized 60 GHz front-ends, including fully differential MMICs, with gain control and phase-shifting capabilities, interconnected to a broadband differentially fed waveguide for the WR-15 standard. The front-ends were designed based on MMICs using 0.25 μm SiGe BiCMOS and packaging on low-temperature-cofiredceramics (LTCC) technology. We have designed, simulated, fabricated, and tested the front-ends showing a useable bandwidth of more than 12 GHz at the 60 GHz band fulfilling the requirements of the IEEE 802.11ad standard.

LTCC has also been proven a viable platform for integration of power amplifiers and other active components with respect to thermal dissipation [6]. These active components are mounted on top of the LTCC and connected to the passive functions inside the module per wire-bond, flip chip and surface mount technology or combinations thereof.…”

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 50mm² all required passive and active functions for 1x2 (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.
