Profs. Krishnaswamy and Kinget Win $1.13M DARPA Contract to Develop RF FPGAs
August 07, 2012
Professors Harish Krishnaswamy (PI) and Peter Kinget (Co-PI) have been awarded a four-year $1.13M DARPA contract under the MTO's RF-FPGA program for their research effort titled "CMOS RF Field-Programmable Full-Duplex T/R Module." The goal of the DARPA RF-FPGA program is to develop field-programmable, fully adaptable, and waveform- agnostic integrated RF front-ends and associated design tools for next-generation military cognitive communications, radar and electronic warfare platforms. The Columbia research program will focus on novel receive/transmit modules that are field programmable and can operate under full duplex operation for enhanced spectral efficiency. This includes realizing a new architecture for watt-class, waveform-adaptive, RF CMOS power amplifiers that can function across a wide range of frequencies, operating modes, architectures and power levels while targeting record peak and average efficiency levels. Reconfigurable low-noise amplifiers will be developed that are immune to the presence of the large transmitter signals to enable simultaneous signal reception and transmission.
