PE70A1046

Overview

The Pasternack PE70A1046 is a push-button step attenuator designed for RF applications operating from DC to 2.5 GHz. It features a 75 Ohm impedance with BNC female connectors on both input and output ports. The device provides a total attenuation range of 0 to 91 dB, utilizing discrete steps of 1, 2, 4, 8, 16, 20, 20, and 20 dB. It is rated for a maximum power handling capacity of 2W.

Feature Summary

• Push-button mechanical interface for rapid attenuation adjustment
• 75 Ohm impedance compatibility for standard video and RF systems
• Discrete binary-weighted step configuration for precise signal control

Applications

• RF test and measurement setups requiring variable signal reduction
• Video distribution systems needing impedance-matched attenuation
• Signal chain calibration and level adjustment in broadcast environments

Procurement Notes

Verify the specific connector gender and impedance requirements against your system design before ordering. Confirm that the 2W power rating aligns with your operational signal levels. Ensure the BNC interface matches existing cabling infrastructure. Check for any environmental specifications if outdoor or harsh conditions are involved.

Selection Notes

Select this model when 75 Ohm impedance is mandatory for system integrity. Choose this unit over adjustable continuous attenuators when discrete, repeatable step changes are required. Consider the 2.5 GHz frequency limit to ensure it covers your highest operational frequency. Evaluate the physical size constraints as this is an inline module.
