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 85

°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

crossover will perform reliably as long as the input

power is derated to the curve above.
