PE70A5018

Overview

The Pasternack PE70A5018 is a TTL-controlled programmable RF attenuator module designed for high-frequency applications. It operates within a frequency range of 1 GHz to 20 GHz and provides a maximum attenuation of 127.5 dB. The device features an 8-bit resolution with a step size of 0.5 dB, allowing for precise signal level adjustments. It utilizes SMA female connectors and maintains a 50 Ohm impedance system. The unit is constructed as a modular component with field-replaceable SMA interfaces, suitable for integration into automated test equipment or communication systems requiring digital control.

Feature Summary

• TTL-controlled digital programming interface for automated operation
• High-resolution 8-bit attenuation steps for precise signal management
• Field-replaceable SMA connector design for maintenance flexibility
• Wideband operational capability extending up to 20 GHz

Applications

• Automated radio frequency test and measurement systems
• Digital communication link signal conditioning
• Radar system calibration and testing
• Satellite ground station equipment

Procurement Notes

Verify the specific datasheet version for the exact TTL logic voltage levels and pinout configuration required for your controller interface. Confirm that the operating environment temperature ranges align with the module specifications. Ensure that the SMA connectors are compatible with your existing cabling infrastructure. Check for any updated compliance certifications relevant to your region before finalizing the purchase order.

Selection Notes

Select this model when digital control over attenuation values is required in the 1-20 GHz spectrum. The 0.5 dB step size offers higher precision than standard fixed-step attenuators. Consider the modular form factor if space constraints or future maintenance needs dictate field-replaceable components. Validate that the TTL input signals match the control electronics available in your system architecture.
