Multi-Octave, High Power Efficiency Active Electronically Scanned Array (AESA)

Parry Labs proposes a non-traditional approach to solve the requirements stated in SBIR N201-012, Multi-Octave, High Power Efficiency Electronically Steerable Array (AESA).  The design will employ a novel and disruptive technique in order to meet bandwidth, efficiency and power over the target frequency range of 2 to 4GHz.  Our solution is to combine several amplifier design techniques, the fundamental being a Load-Modulated Balanced Amplifier, or LMBA.  Compared to traditional Doherty, Out-Phasing, class J, or switched mode PA’s, the LMBA offers unique advantages over bandwidth and efficiency.   It employs a simple and cost-effective architecture using many off-the-shelf components.  Using this approach, Parry Labs will demonstrate through end-to-end simulations greater than 50% efficiency for a 2x2 AESA with 40dBm of output power. Parry Labs has formed a world class amplifier development team with over 85 years of combined power amplifier and RF circuit design experience.  The team’s experience includes designing cellular band RF power amplifiers for Lucent/Bell Labs, Andrew Corporation (now Commscope), and most recently Futurewei Technologies.  The team is excited to utilize their expertise and strong track record of innovation in support of the United States Department of Defense.
