“…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].…”

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

“…Fig.1 shows a general WLAN/WiMAX block diagram for 1x2 MIMO, multiband multimode operation. It is comparable to the typical WLAN architectures [7], [8] and is basically a composition of various WiMAX block schematics suggestions from [9], [10] RF-frontend interfacing between the RFIC and the antenna ports.…”

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.

“…Although LTCC modules for WLAN applications already have secured more than 25 times size reduction compared to the discrete solution [4], even higher levels of integration are needed.…”

In this paper a new approach for miniaturizing multilayer LTCC designs (Low Temperature Co-Fired Ceramics is proposed. Using the stacking options inside LTCC more consequently, a new very compact high-rejection balanced bandpass filter for WirelessLAN (based on IEEE 802.11a standard) is realized. The demonstrated filter performance is a very promising. With only 2.7 dB insertion loss in the band of interest and excellent out-of-band attenuation it occupies area less than 1.8 mm². Compared to designs with the same dielectric constant this downsizes by factor of two the required area without degrading the performance. The correlation between measurement and simulation results is a very good.
