High Dynamic Range Multi-Carrier Amplifier (HDR MCA)

In response to the N181-088 SBIR solicitation ("High Dynamic Range Multi-Carrier Amplifier"), MaXentric proposes EMBARC (Efficient Multi-carrier Broadband Amplifier for Radio Communication) to overcome the challenges of multi-carrier, multi-channel amplification. EMBARC supports up to 36 concurrent carriers from with 100W of output power for VHF and UHF systems (2MHz - 3 GHz). Due to the nature of multi-carrier signals (high peak to average power), EMBARC utilizes intelligent supply management as well as Adagio (multi-carrier enabler) coupled with GreenAmp envelope tracking to provide the highest efficiency, keeping the overall SWaP to a minimum. High linearity is achieved with our real-time predistorter MaXPAL. In addition, EMBARC integrates a coupler system to enable future-leaning STaR platforms. To enable smooth integration with existing and future platforms, EMBARC is designed to interface with the digital modular radios (DMR). In Phase I, the analysis and design of EMBARC will be performed through simulations along with relevant trade studies. The effort includes a feasibility demonstration of EMBARC. Phase II efforts involve the implementation, fabrication, and system integration of EMBARC, resulting in a hardware prototype-based design methodology and findings of Phase I.
