PDF File
These are RF and
microwave resistors of 50 to 800ohms with flange cooling. These are
also applicable for terminations in strip-line circuits. Long life and
temperature stability
are the result of Ni-Cr thin film and super heat conductive ceramic
substrates. Applications
include: Industrial RF power sources, RF amplifiers, radio transmitters,
fixed transmitters
of mobile systems and measurements.
