IRC TT HFR-PAT3042PLF-50R0-09-B High power flanged attenuator Datasheet

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.
