High Frequency
Surface Mount Attenuators
RFAXXX-0 Series
•
RoHS compliant
•
Power dissipation up to 150W
•
High frequency operation up to 3GHz
The RFAXXX-0 series power attenuator has a low VSWR from DC to 3GHz. High frequency performance
combined with high power dissipation make this an ideal RF power attenuator. Typical applications are RF and
microwave power amplifiers, RF transmitters, receivers and meters where a reduction in power is needed while
maintaining transmission line characteristic impedances.
