Insertion Loss Derating:
Power 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 85C and 140C. A best-fit line for
the measured data is computed and then plotted from -
55C to 140C.
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.
