Flanged RF
Power Terminators
RFRF Series
•
High power dissipation to 250W
•
Flange cooling for stripline circuit terminators
•
Long life, temperature stable thin film on ceramic technology
The RFRF series of high power transmission line terminators and loads
make use of a flanged heat sink construction producing power ratings up
to 250W and operation to 3GHz. Ohmic values are available in 50Ω, 100Ω, 150Ω and 200Ω nominal values for
maximum flexibility in your high frequency layout and design. Ideal for use in industrial RF power sources, RF
amplifiers, transmitter systems and mobile RF designs.
