The ACST 1221B-36S Broadband Source is a high-performance in-housing millimeter-wave signal source designed for wideband RF and microwave applications requiring stable, low phase-noise output. It integrates a voltage-controlled oscillator (VCO) with an active amplification and multiplication chain to deliver precise signal generation across the 500 to 750 GHz range. The unit is housed in a compact metallic enclosure with standardized RF and DC interfaces for seamless integration into laboratory, radar, and measurement systems.
