c) Reliability Considerations
This procedure yields the upper limit for the power dissipation for continuous wave (cw) and
pulse applications which corresponds to the maximum allowed channel temperature. For
best reliability keep the channel temperature low. The following formula allows to track the
individual contributions which determine the channel temperature.
