W-Band High-Power Chirped Solid-State Transmitter Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-110 Topic Title: W-Band High-Power Chirped Solid-State Transmitter Proposal No.: N052-110-0053 Firm: QuinStar Technology, inc. 24085 Garnier Street Torrance, California 90505 Contact: Robert Ying Phone: (310) 320-1111 Web Site: www.quinstar.com Abstract: By capitalizing the high power capability of the W-band series stacked pulsed IMPATT diodes, and a hybrid-coupled combiner, pulse power output greater than 50 watts can be achieved from a transmitter, more than twice the output power currently achieved from a single junction device, but small enough to be gimbal mounted. Injection locking the combiner to the pulsed frequency chirping IMPATT oscillator currently used in HARM development, the high output power will have the necessary pulse compression characteristics of the locking oscillator. The higher power output will enable the HARM to have longer range and more robust performance. Benefits: The millimeter-wave transmitter will form the basis for wide applications in the area of missile seekers, airport traffic control and monitoring, altimeters, motion detectors such as those used in security systems, automotive adaptive cruise control and collision avoidance, personnel detections for the law enforcement agencies.
