Import Directional Coupler — Buy in Bulk from Supplier in Taiwan

The Tien Tai Electronic Co. Ltd. directional coupler is a passive RF component designed to sample forward and reflected power in transmission lines, typically used in telecommunications and broadcast systems. It operates across frequencies from 50 MHz to 3 GHz, with coupling factors of 10 dB, 20 dB, or 30 dB, and insertion loss under 0.5 dB. The unit is housed in a shielded metal enclosure with SMA or N-type connectors, matching standard coaxial system interfaces.

This coupler uses precision microstrip or hybrid coupler technology, common in high-frequency applications. The internal components are made from low-loss dielectric substrates with gold-plated contacts to ensure stable performance under thermal cycling. Typical isolation exceeds 20 dB, and directivity is maintained above 15 dB across its rated bandwidth. These are standard performance benchmarks for industrial-grade directional couplers, not guaranteed by the supplier but aligned with industry norms.

Buyers in the telecom infrastructure, radar, and test equipment sectors use this device for power monitoring, VSWR measurement, and signal sampling. The product is supplied in bulk packaging of 50 units per carton, with each unit individually wrapped in anti-static material. Lead time is not specified; buyers should confirm delivery schedules directly. Incoterms such as FOB Tainan Port are available upon request, and minimum order quantities are not listed.
