WR3.4 Waveguide Multiplier 220-330 GHz for Sub-Terahertz Applications
The AT-AM18-220330 is an X18 active frequency multiplier engineered to operate across the entire 220–330 GHz band. This waveguide-based component addresses the growing demand for compact, efficient sub-terahertz signal sources in research, imaging, and advanced RF systems.
The multiplier converts microwave input signals into high-frequency output by applying an 18× multiplication factor. The device accepts RF input between 12.22 GHz and 18.33 GHz via SMA female connector and delivers multiplied signals through a WR-3.4 waveguide interface equipped with UG-387/M anti-cocking flange. Integrated buffer stages ensure stable performance while maintaining low drive requirements, simplifying integration into diverse system architectures.
