RFTL - Willow Technologies

RF SOLUTION - NIKKOHM
LEADED HIGH POWER TERMINATIONS
RFTL
Features and Applications
High power surface mount termination for all DC up to 3GHz applications.
Small size and wide frequency range specifications realized with large heat conducting AlN substrate.
Sufficient mechanical strength metallization comes from spattered thin film technology.
50ohm, 100ohm and 200ohm resistance with tolerance 1% and 10W, 20W, 30W, 150W and 250W
provided as standard, and other resistance and power also available.
Long life and temperature stability a result of Ni-Cr thin film technology.
Applications include power splitters, power combiners, balancing resistors, termination for wide band
transformer circuits and termination for isolator/circulators, fixed station of mobile communication
electronics, and high power microwave amplifiers.

Heat sink temperature.(C)
Note:
(1) Rated power is defined at attached on a heat-sink plate of +25 C temperature by soldering. When
higher temperature, power shall be derated as above shown curve.
(2) Termination has two terminals, one is plate tab terminal and other is backing plate that will be attached
on heat sink by soldering.
(3) There is no mechanical moving or vibration between strip terminal attached on strip line circuit and heat
sink.
(4) Other resistance value are available. Please call factory.
