Mounting Interface Temperature (^oC)
Insertion Loss Derating:
The insertion loss, at a given frequency, of a group of
couplers is measured at 25C and then averaged. The
measurements are performed under small signal conditions
(i.e. using a Vector Network Analyzer). The process is
repeated at 95C and 150C. A best-fit line for the
measured data is computed and then plotted from -55C to
150C.
Power Derating:
The power handling and corresponding power derating
plots are a function of the thermal resistance, mounting
surface temperature (base plate temperature), maximum
continuous operating temperature of the coupler, and
the thermal insertion loss. The thermal insertion loss is
defined in the Power Handling section of the data sheet.
As the mounting interface temperature approaches the
maximum continuous operating temperature, the power
handling decreases to zero.
If mounting temperature is greater than 95C, Xinger
coupler will perform reliably as long as the input power
is derated to the curve above.
