Next Generation Portable Power Amplifier

In response to the SOCOM 13-004 Next Generation Portable Power Amplifier solicitation, MaXentric proposes the GreenAmp-lite system. The GreenAmp- & #8208;lite combines MaXentric"s envelope tracking technology with a power amplifier MMIC in a single small footprint package. This tight integration is made possible through the extremely high efficiency and low power dissipation provided by envelope tracking. Since very little power is dissipated as heat, the package and heat sink size can be minimized. Integration has benefits in terms of cost and reproducibility as well. The RF PA MMIC requires no calibration or tuning allowing GreenAmp- & #8208;lite modules to be directly plugged into systems out of the box. The system leads to a minimization of weight, heat and bulk. This allows for a system where the battery can be reduced in size and integrated into the handheld PA device. During Phase I the GreenAmp-lite system will be compared to alternate PA designs and compared in terms of weight, heat, bulk and feasibility. Conceivable systems, which meet or exceed the specifications outlined in the SOCOM 13-004 SBIR solicitation, will then be ranked in terms of complexity, performance and realizability.
