PE70A1040B

Overview

The PE70A1040B is a push-button step attenuator manufactured by Pasternack. It operates within a frequency range of 0 Hz to 1 GHz and provides an attenuation range of 0 dB to 90 dB with a step resolution of 1 dB. The device features BNC female connectors on both input and output sides, maintaining a characteristic impedance of 50 Ohms. It is designed as an in-line module capable of handling up to 2W of power.

Feature Summary

• Push-button step control mechanism for precise attenuation adjustment
• In-line module form factor with BNC female-to-female connectivity
• Wide attenuation range from 0 to 90 dB with 1 dB step resolution

Applications

• RF signal level adjustment in test and measurement setups
• Attenuation in telecommunications equipment
• Instrumentation signal conditioning

Procurement Notes

Verify the specific datasheet version for detailed electrical specifications such as VSWR and insertion loss. Confirm connector gender and interface type matches system requirements. Ensure power rating compatibility with operational signal levels. Check for any environmental operating constraints specified by the manufacturer.

Selection Notes

Select this component when fixed-step attenuation is required rather than continuous variable adjustment. The BNC interface suits standard laboratory and industrial RF environments. Consider the 1 dB step resolution for applications requiring fine-grained signal control within the 0-90 dB range.

Part Context

This part belongs to Pasternack's line of RF attenuators, specifically designed for coaxial applications. It serves as a passive component for managing signal strength in radio frequency circuits. The product is categorized under interconnects and RF components, distinct from adapters or active devices.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing circuitry before considering alternative models from other manufacturers.
