ZOMWAVE Directional Couplers are passive devices that sample part of the power traveling through a transmission line, helping RF engineers control signal flow and monitor system behavior more accurately. Built for demanding RF and microwave designs, these Directional Couplers offer strong bandwidth, high directivity, and higher power handling for cleaner signal sampling and more stable measurement paths. Many models are RoHS and REACH compliant, giving you a practical choice for regulated projects.
ZOMWAVE’s RF Directional Couplers are available with N-type or SMA connectors, and the category includes coupling values such as 6 dB, 10 dB, 16 dB, 20 dB, 30 dB, and 35 dB. The listed products cover power ratings from 25 Watts to 70 Watts, with frequency coverage from 1 GHz to 8 GHz, and selected models, such as the 30 dB N Type coupler and 20 dB N Type coupler, show low insertion loss, controlled VSWR, and operating temperature ranges suited to real-world RF environments.
ZOMWAVE’s directional coaxial coupler category currently shows 20 results, and the site highlights 5-day shipping for fast fulfillment from a broad RF and microwave inventory. That helps reduce sourcing delays, support faster project turnaround, and keep measurement, feedback, and signal sampling tasks moving with less interruption across lab and field applications.
