The ACST 1219H-18AC Compact Broadband AMC is a high-performance active multiplier chain designed for broadband millimeter-wave signal generation in the 250 to 370 GHz range. Built on ACST’s high-power broadband multiplier and ERZIA amplifier technology, it delivers efficient, low-noise frequency multiplication with excellent spectral purity and flat broadband response. Engineered for laboratory instrumentation, FMCW radar systems, active imaging, and LO generation for sub-THz receivers, it provides a compact, fixed-tuned solution with standard RF interfaces and optional output customization.
