PE70A1040S

Overview

The PE70A1040S is a push-button step attenuator manufactured by Pasternack, designed for RF interconnect applications. It features SMA female connectors and operates within a frequency range of 0 Hz to 1 GHz. The device provides an attenuation range of 0 to 90 dB with 1 dB resolution steps. It has a power rating of 2 Watts and a characteristic impedance of 50 Ohms. The unit maintains a VSWR of 1.5:1 and functions within a temperature range of -20°C to +85°C.

Feature Summary

• Push-button control mechanism for precise step attenuation adjustments
• SMA female-to-female connector interface for seamless integration
• High attenuation range up to 90 dB with fine 1 dB step resolution

Applications

• RF signal testing and measurement setups
• Calibration of radio frequency equipment
• Signal level adjustment in communication systems

Procurement Notes

Verify the specific datasheet version for the PE70A1040S to confirm current manufacturing status and compliance details. Ensure that the SMA connector gender and impedance match system requirements before ordering. Check for any recent updates to the RoHS certification or environmental operating limits provided by Pasternack.

Selection Notes

Select this model when a wide dynamic range of attenuation is required at frequencies up to 1 GHz. The 2W power rating suits moderate signal levels. Consider the physical size and push-button interface requirements against other variable attenuator types if space or remote control is a constraint.

Part Context

This component belongs to Pasternack's line of connectorized attenuators, specifically the RF Variable Attenuators series. It complements fixed and continuously variable models by offering discrete step control. The product supports various RF test and measurement environments requiring reliable signal reduction.

Replacement Considerations

No public confirmed substitute part numbers are available in the source data. Evaluate other Pasternack models like the PE70A1047S or PE70A1049S only if higher frequency ranges or different attenuation steps are acceptable.
