WMDDC-2-18-10dB is a true dual directional coupler that covers 2 to 18GHz with 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. Insertion loss 1.85dB typical. Directivity 17dB typical. Return loss 20dB typical.
