System-in-Package solutions for WiMAX applications based on LTCC technology

This paper presents a dual-band (2 and 3 GHz) and a single-band (2GHz) highly-integrated WiMAX System-in-Package module based on LTCC (Low Temperature Cofired Ceramics). They comprise of complete passive and active RF frontend plus the RFIC for up- and down-conversion to the base band. Both modules support 1×2 (1 transmit, 2 receive paths) MIMO operability. The top level measurements of the SiPs show full performance and thus fully validate the LTCC integration approach.
