The ACST 1221A-54S Broadband Source is a high-performance in-housing millimeter-wave signal source designed for ultra-wideband applications operating from 750 to 1100 GHz. It utilizes a voltage-controlled oscillator followed by a high-power amplifier/multiplier chain to deliver stable output power across the full WR-1.0 waveguide band. The module is housed in a compact metallic enclosure with integrated power supply and standard RF/DC interfaces for seamless laboratory or system integration.
