A low cost, ultra small antenna integrated wireless transceiver is one of the key technologies for short range millimeter-wave wireless communication. A RF module with integrated antenna will be presented. It consists of low cost organic multi-layer substrates and MMICs. The substrates are vertically stacked by employing Cu ball bonding 3-D system in package (SiP) technology and MMIC's are mounted on the organic substrates by using stud bump bonding (SBB) technique. The antenna performance with RF module will be presented. The results show the feasibility of millimeter-wave low cost, ultra small antenna integrated module using organic substrates.
