IRC Advanced Film Division
The PAT-P series power attenuator has a very low VSWR from DC to
10 GHz. High frequency performance combined with high power dissipa-
tion make this an ideal RF power attenuator. Typical applications are power meters and amplifiers where a
reduction in power is needed while maintaining transmission line characteristic impedances.
