Microwave Filter Company DC-2018-050-10SF Directional Coupler, 2-18 GHz, 10dB, SMA Female

DC-2018-050-10SF is a directional coupler that covers 2 to 18 GHz with broadband flat coupling response, high directivity, and excellent return loss performance. Frequency sensitivity, or coupling flatness, is very good, with ±0.3dB typical. The aluminum enclosure measures 2.25 x 0.73 x 0.50 inches with threaded mounting holes. Coupling flatness ±0.35dB typical. Insertion loss 0.8dB typical. Directivity 17B typical. Higher directivity is available on special order. Return loss 19dB typical. SMA Female connectors. The device is RoHS complaint, but Sn/Pb solder is available for military applications on special build to order. The device covers the letter bands S, C, X and Ku band all in one enclosure. Our own unique coupling design allows for excellent flatness, thereby increasing measurement accuracy. Designed, assembled and tested in the USA.

DC-2018-050-20SF is a directional coupler that covers 2 GHz to 18 GHz with broadband flat coupling response, typically ±0.45dB, high directivity, and excellent return loss performance. Return loss is 18dB typ. Directivity 17dB typical. Higher directivity is available on special order. Coupling flatness ±0.45dB typical. Insertion loss 0.8dB typical. The enclosure is aluminum with threaded mounting holes. Stainless steel SMA female connectors for rugged, reliability. RoHS complaint however lead solder is available on special order. Our unique approach as the design of the coupling segment provides excellent ripple performance, thereby providing highly accurate measurements across the bands. Such bands include S band, C band, X band and Ku band. Assembled and tested in the USA.
