Incident power (dBm)
The CHE1260-98F is a bidirectionnal detector using a symmetrical bidirectionnal coupler.
Therefore the incident power detection versus incident power is identical to the reflective
power detection versus reflected power.
The reflective power detection versus incident power depends on both the coupler directivity
and the reflective environment of the chip.
