Dual-Directional Couplers
ACST’s 532x Series Dual-Directional Couplers are precision-engineered four-port passive devices designed for power monitoring and signal sampling in millimeter-wave systems. Covering a broad frequency range from 50 to 500 GHz, these couplers deliver high directivity, low insertion loss, and a flat coupling response across their respective bands. Each unit is manufactured using ACST’s advanced high-tolerance machining process, ensuring excellent repeatability and phase stability for critical test setups and system integration. Their compact, gold-plated brass construction provides superior conductivity and mechanical durability for long-term use. These couplers are well-suited for applications in power detection, amplifier characterization, and measurement setups requiring bidirectional coupling accuracy. Custom or asymmetrical coupling values are available upon request.
