PE7020-40

Overview

The Pasternack PE7020-40 is a fixed RF attenuator module providing 40 dB attenuation. It operates from 0 Hz to 18 GHz with a 50 Ohm impedance. The device handles up to 50 Watts of power at the stated attenuation value. It features SMA male to SMA female connectors and utilizes a black anodized aluminum heatsink body for thermal management.

Feature Summary

• Directional design utilizing a black anodized aluminum heatsink body for effective thermal dissipation
• SMA male to SMA female connector interface ensuring compatibility with standard coaxial systems
• Fixed 40 dB attenuation rating maintained across a wide frequency range up to 18 GHz

Applications

• RF signal level reduction in microwave test and measurement setups
• Impedance matching and isolation in high-frequency communication circuits
• Power handling in RF transmission lines requiring precise attenuation

Procurement Notes

Verify the specific datasheet revision and connector gender configuration before ordering. Confirm that the 50W power rating aligns with your system's peak power requirements. Ensure the SMA interface matches your existing cabling infrastructure. Check for any environmental operating limits specified in the official documentation.

Selection Notes

Select this model when a fixed 40 dB attenuation is required within the 0 Hz to 18 GHz spectrum. The 50W power handling capability makes it suitable for higher power applications compared to standard low-power attenuators. The directional design aids in minimizing reflections, which is critical for maintaining signal integrity in sensitive RF environments.

Part Context

This component belongs to Pasternack's series of fixed RF attenuators designed for microwave and millimeter-wave applications. The PE7020 series typically offers various attenuation values while maintaining consistent impedance and connector types. These modules are engineered for reliability in demanding RF environments, providing stable performance across wide bandwidths.

Replacement Considerations

Check for equivalent models from Pasternack such as the PE7020-30 or PE7020-20 if different attenuation values are needed. Ensure any substitute maintains the same 50 Ohm impedance and SMA connector type. Verify that the replacement part supports the required 18 GHz frequency range and 50W power handling capacity.
