PE7049-20

Overview

The Pasternack PE7049-20 is a fixed coaxial attenuator designed for RF signal management. It provides a precise attenuation value of 20 dB with a 50 Ohm impedance system. The device utilizes BNC connectors, featuring a male interface on one side and a female interface on the other. It operates within a frequency range extending up to 4 GHz and supports a maximum power rating of 2 Watts. The construction employs a brass body with nickel plating for durability.

Feature Summary

• Fixed resistive PI attenuator pad design
• Brass tri-metal body with nickel finish
• In-line coaxial configuration

Applications

• RF signal level reduction in test setups
• Impedance matching between circuit stages
• Protection of sensitive receiver inputs

Procurement Notes

Verify the specific connector gender configuration against project requirements, as the model designation implies a male-to-female arrangement. Confirm that the 2 Watt power handling capacity aligns with the peak signal levels present in the intended application path. Ensure the operating frequency does not exceed the 4 GHz upper limit specified for this component series.

Selection Notes

Select this component when a fixed 20 dB reduction is required without variable adjustment capabilities. The BNC interface makes it suitable for benchtop equipment or legacy systems utilizing standard BNC connections. Consider the physical size and mounting requirements associated with the brass nickel body style compared to smaller surface-mount alternatives.

Part Context

This part belongs to the Pasternack PE7049 series of fixed attenuators. The series offers various attenuation values while maintaining consistent mechanical and electrical characteristics across different models. These components are engineered for general-purpose microwave applications requiring stable performance over the specified frequency band.

Replacement Considerations

Direct substitutes include other 20 dB fixed attenuators with BNC male-to-female interfaces and similar power ratings. Verify that any replacement maintains the 50 Ohm impedance and 4 GHz frequency capability to ensure system compatibility.
