1. Input power is rated for load VSWR better than 1.20:1.
2. 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+0.04db coupled loss ).
3. Other configurations, such as different frequencies or different couplines, are available under different part numbers.

We provide ODM&OEM services for you, and can provide 3dB, 6dB, 10dB, 15dB, 20dB, 30dB, 40dB custom couplers respectively. SMA, N-Type, F-Type, BNC, TNC, 2.4mm and 2.92mm connectors are available for your choice.
