TFTF FLANGED TERMINATIONS

Download PDF File

Features and Applications

These are RF and microwave terminations of 50ohms incorporating flanged cooling.  These components
exhibit low return loss, long life and temperature stability.  These characteristics 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 for mobile systems and measurements.
