Abstract: A power amplifier (PA) linearization technique with a wider linearized power range is proposed. Proposed two types of linearizers with cross-coupled PMOS and NMOS configuration. The idea is to use a complimentary device compared with the PA core device, and the behavior of Cgs of the linearizer are also complimentary to the PA itself. In the other words, the overall Cgs of the PA with the linearizer would be constant without leading to non-linear waveform. Both linearizers can effectively compensate not only AMAM but also AMPM. First type of linearizer can be integrated with PA cores, and second type of linearizer can be used in the IMN. Both linearizers have effective IM3 reduction in different corner.

Abstract: An article of manufacture provides a compact assembly of power amplifiers in series and in parallel. A plurality of radial power splitters and radial power combiners couple surface mounted power amplifier dice into a power platter. Thermal conduction probes chained through the power platters remove heat from the vicinity of the power amplifier dice. Surface mounted power amplifier dice may be enclosed within a matched pair of power platters. Stackable power platters may be assembled to form a 3D power amplifier pile.

Abstract: A peripheral apparatus includes an application program. The peripheral apparatus couples to the host system and automatically install the application program into the host system. Thus, the peripheral apparatus of the present invention does not need extra floppy disks or CD-ROM containing the application program. This aspect of the present invention is to avoid intervention for user, e.g., losing the floppy disks or CD-ROM.
