The operating power gain (also known as the power gain) is the ratio of the power delivered to the load to the power input from the source. The power gain is given by
GP = PPower delivered to the load / PPower input to the network
The power gain is computed from
where Γin, the reflection coefficient looking into the input, is given by
You can use this measurement on documents with more than two ports. To port and From port identify the output and input ports respectively. The simulator reduces the NxN circuit and noise parameter matrices to 2x2 matrices, which allows the measurement calculation to proceed as normal. The matrix reduction takes into account the port terminations of the ports not being used by the measurement. For example, if you are measuring GP2(2,1) on a 4-port schematic, ports 3 and 4 are terminated with their port impedance. This is equivalent to creating a test bench with the 4-port DUT and terminating ports 3 and 4 manually. Port impedances contribute to noise as expected and scale their contribution with _TEMPK. For data files and EM structures, ports not being used by the measurement are terminated in 50 ohms.

NOTE: All measurements will have additional parameters that allow you to specify the plotting configuration for swept parameters. These parameters are dynamic; they change based upon which data source is selected. See “Swept Parameter Analysis ” for details on configuring these parameters.
