Utilizing our well-known experiences of RF/Microwave Control Components and High Power Amplifiers, Daico introduced a Game Changing transmitter (m+n)ART architecture, Part Number CTX09500, that delivers 14kW power at L-Band with unprecedented Availability, Reliability, and Maintainability. CTX09500 was deployed for a mission critical ASR-3 transmitter upgrade in 2010. It is featured with automatic failover, graceful power degradation and true “hot-Swap” capability for an uninterrupted operation. The (m+n) Automatic Redundancy Technology were awarded with six patents. With sponsors of two SBIR.II programs, Daico had further developed a CHPA (Combined High Power Amplifier) Building Block with ultra-high reliability outperforming Klystron and TWT technologies. This flexible and scalable CHPA transmitter architecture can be implemented to achieve hundreds of kW power at up to C-Band in an air or liquid cooled environment.
