The ACST 1221A-54A Broadband AMC is a high-performance active multiplication chain module engineered for ultra-wideband sub-THz and terahertz signal generation applications. Designed to extend the operating frequency range of microwave signal synthesizers and sweepers, this module delivers stable high-frequency output across the 750 to 1100 GHz band with excellent spectral purity, flat broadband response, and high-efficiency multiplication performance. Its robust in-housing metallic design, integrated power supply system, and plug-and-play architecture make it ideal for laboratory instrumentation, mm-wave FMCW radar, active imaging, and LO source applications.
