Determination of Permissible Total Power Dissipation for Continuous and Pulse
Operation
The dissipated power is the power which remains in the chip and heats the device. It
does not contain RF signals which are coupled out consistently.
a) Continuous Wave/DC Operation
For the determination of the permissible total power dissipation Ptot-DC from the diagram
below it is necessary to obtain the temperature of the soldering point TS first. There are
two cases:
•
When RthSA (soldering point to ambient) is not known: Measure TS with a temperature
sensor at the leads were the heat is transferred from the device to the board
(normally at the widest source or ground lead for GaAs). Use a small sensor of low
heat transport, for example a thermoelement (< 1 mm) with thin wires or a
temperature indicating paper while the device is operating.
•
When RthSA is already known: TS = PDiss × RthSA + TA

b) Pulsed Operation
For the calculation of the permissible pulse load Ptot-max the following formula is
applicable:
Ptot-max = Ptot-DC × Pulse factor
= Ptot-DC × (Ptot-max/Ptot-DC)
Use the values for Ptot-DC as derived from the above diagram and for the pulse factor =
Ptot-max/Ptot-DC from the following diagram to get a specific value.

Ptot-max should not exceed the absolute maximum rating for the dissipated power
PPulse = “Pulse peak power” = 2 W
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.
