RFAXXX-0 Series

High Frequency

Surface Mount Attenuators

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.
