Explanation of Specifications
This tab provides a brief explanation of how we determine several key specifications for our 1x2 couplers. The legs of the coupler are defined as shown in the diagram below.
Figure does not represent a specific coupling ratio (for demonstrational purposes only)
Excess Loss Excess loss in dB is determined by the ratio of the total output power to the total input power:
Pport1 is the input power at port 1 and Pport2+Pport3 is the total output power from Ports 2 and 3. All powers are expressed in mW.
