This paper presents the development of RF System-on-Package (SOP) architectures for compact and low cost wireless radio front-end systems. We present multi-layer Ceramic-based module development such as a 2.4 GHz SiGe HBT power amplifier module with a harmonic suppression filter implemented in LTCC substrate and a via-fed stacked cavity-backed patch antenna designed to fully cover the required band (5.725-5.825 GHz). Multi-layer organic packaging development for SOP is reported. A C-band up-converter MMIC integrated with a square patch resonator band pass filter and an Intelligent Network Communicator (INC) RF block are presented as example of the high performances of multi-layer organic package.
