PE7021-20

Overview

The Pasternack PE7021-20 is a fixed 20 dB attenuator designed for RF applications up to 1.5 GHz. It features a resistive PI attenuator pad topology and operates within a 50 Ohm impedance system. The device is rated for a maximum power handling capacity of 100 Watts at the stated attenuation value. It utilizes Type-N connectors, specifically N Male on one side and N Female on the other, ensuring compatibility with standard coaxial systems.

Feature Summary

• Fixed 20 dB attenuation value
• Resistive PI attenuator pad design
• Type-N male to female connector interface
• Black anodized aluminum heatsink body

Applications

• RF signal level reduction in microwave systems
• Impedance matching between 50 Ohm components
• Signal attenuation in test and measurement setups

Procurement Notes

Verify component status as the PE7021-20 is listed as obsolete and no longer manufactured by Pasternack. Confirm availability through authorized distributors or check for parametric equivalents from other manufacturers such as Amphenol Procom before finalizing procurement plans.

Selection Notes

Select this component only if a fixed 20 dB attenuation at 100 Watts within a 1.5 GHz bandwidth is required. Ensure the system supports Type-N connectors and 50 Ohm impedance. Consider alternative active or variable attenuators if adjustable attenuation is needed instead of a fixed value.

Part Context

This part belongs to the Pasternack PE7021 series of fixed attenuators. Similar models include the PE7021-6 (6 dB), PE7021-10 (10 dB), and PE7021-40 (40 dB). All share the same directional black anodized aluminum heatsink construction and 100 Watt power rating up to 1.5 GHz.

Replacement Considerations

Available substitutes include parametric equivalents from manufacturers like Amphenol Procom. Verify that replacement parts match the 20 dB attenuation, 100 Watt power rating, and Type-N connector gender configuration.
