RF SOLUTIONS - WILLOW TECHNOLOGIES LTD
FLANGED TERMINATIONS
RFTF
Features and Applications
RF and microwave termination of 50ohm have flange cooling.
Low return loss, long life and temperature stability a result of Ni-Cr thin film and super heat conductive
ceramic substrates.
Industrial RF power sources, RF amplifiers, radio transmitters, fixed transmitter of mobile systems, and
measurements.
