RF Passive Wideband Coaxial 30dB Directional Coupler



  •  Performances can be optimized for the forward path •  High directivity and isolation •  Low Insertion Loss •  Directional, Bidirectional, and Dual Directional are avaliable   Directional couplers are an important type of signal processing device. Their basic function is to sample RF signals at a predetermined degree of coupling, with high isolation between the signal ports and the sampled ports

1. Input power is rated for load VSWR better than 1.20:1. 2. Specifications are subject to change at any time without any notice. 3. The physical loss of the coupler from input to output in the specified frequency range. The total loss is the sum of the coupled loss and the insertion loss. (Insertion loss+0.004db coupled loss ). 4. Other configurations, such as different frequencies or different couplines , are available under different part numbers. OEM and ODM servies are welcomed, 3dB, 6dB, 10dB, 15dB, 20db, 30dB, 40dB and 50dB customized couplers are avaliable. SMA, N-Type, F-Type, BNC, TNC, 2.4mm and 2.92mm connectors are avaliable for option.
