PE70A8002

Overview

The PE70A8002 is an 8-bit relay-controlled programmable attenuator manufactured by Pasternack. It provides a maximum attenuation of 63.75 dB with 0.25 dB step resolution across a frequency range of 0 Hz to 2 GHz. The device operates on a +12V supply and features SMA female connectors. It has a 50 Ohm impedance, a power rating of 500 mW, and is designed as an in-line module.

Feature Summary

• Eight-bit digital control architecture for precise attenuation adjustment
• Relay-based switching mechanism ensuring signal integrity
• Fine 0.25 dB step resolution for detailed signal management

Applications

• Automated RF test and measurement systems
• Programmable gain amplifier circuits
• Signal conditioning in communication equipment

Procurement Notes

Verify the specific datasheet version for the PE70A8002 to confirm pinout configurations and control logic levels. Ensure the +12V supply requirement aligns with system power constraints. Confirm SMA connector compatibility with existing cabling infrastructure before integration.

Selection Notes

Select this component when precise, digitally controlled attenuation is required up to 2 GHz. The 8-bit resolution offers finer granularity than standard fixed or coarse-step attenuators. Consider the 500 mW power limit and +12V drive requirement during system design.

Part Context

This part belongs to Pasternack's line of connectorized attenuators. It differs from the PE70A1047S (fixed step) and PE70A8003 (75 Ohm, lower frequency). It serves as a programmable solution for dynamic signal level adjustment in RF environments.

Replacement Considerations

No direct public substitute part numbers are confirmed for the PE70A8002. Alternative solutions may require custom programming or different form factors.
