Prof. Krishnaswamy's Group Featured by DARPA
Assistant Professor Harish Krishnaswamy's group's research and contributions have recently been featured on DARPA's website. Under the DARPA ELASTx program, the CoSMIC lab recently demonstrated a world-record power amplifier in CMOS that generates watt-level output power at millimeter-wave frequencies. The result will be presented by CoSMIC lab students at the upcoming IEEE RFIC Symposium conference to be held in Seattle in June.
Millimeter-wave power amplifiers have been demonstrated at this power level before, but this is a record with silicon-based technologies, said Sanjay Raman, DARPA program manager. Producing this level of output with silicon may allow integration on a chip with complex analog and digital signal processing. In the 42-25 GHz range, this would enable high bandwidth/data-rate transmitters needed for satellite communications at potentially very low cost and size, weight and power.
