MODEL NUMBER DESCRIPTION:

Example:

POWER RATING (mounted horizontally): 50 watts

average (unidirectional) to 25°C ambient temperature,

derated linearly to 5 watts @ 125°C. Note: 3 dB model can

handle 100 Watts average (unidirectional). 1 kilowatt

peak (5 μsec pulse width; 2.5% duty cycle). Maximum

power rating into output port is 10 Watts average.
