High Power Flanged Attenuators PAT-P Series • Power dissipation up to 10W • High frequency operation up to 10GHz • Flanged package for heat sink mounting The PAT-P series power attenuator has a very low VSWR from DC to 10GHz. High frequency performance combined with high power dissipation 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.
