Lead Free RF SOLUTION - NIKKOHM SURFACE MOUNT HIGH POWER TERMINATIONS RFTS Features and Applications High power surface mount termination for all DC up to 6GHz applications. Small size and wide frequency range specifications realized with through large heat conducting AlN substrate. Sufficient mechanical strength metallization from spattered thin film technology. 50ohm and 75ohm resistance with tolerance 1% and 10W, 50W, 100W and 250W provided as standard, and other resistance and power available. Long life and temperature stability a result of Ni-Cr thin film technology. Flanged termination will be available in the RFTF series. Termination for isolator/circulators, fixed station of mobile communication electronics, and high power microwave amplifiers.
