888-498-3242 
Description
The WMDDC-2-18-10dB-S is an SMA female Dual Directional Coupler with a wide frequency range spanning from 2 GHz to 18 GHz by Werbel Microwave. Features excellent return loss, coupling flatness and high directivity. Its advantage is a smaller and more lightweight housing than two independent couplers. It eliminates reflections caused by additional cabling. Improved performance over separate couplers due to the lack of interconnections and cable between. Designed, assembled, and tested in USA with lead free solder making it RoHS compliant. Werbel Microwave Cage Code: 78YZ0.
