PE70A5009

Overview

The Pasternack PE70A5009 is a TTL-controlled programmable RF attenuator module featuring SMA female connectors. It provides an attenuation range of 0 to 63 dB with 1 dB step resolution across six bits. The device operates within a frequency range of 200 MHz to 6 GHz and maintains a 50 Ohm impedance. It is designed for applications requiring precise digital control of signal levels in coaxial systems.

Feature Summary

• TTL-controlled digital interface for automated signal attenuation
• Six-bit resolution providing 1 dB step increments
• SMA female connectorized module design

Applications

• Automated test equipment signal conditioning
• RF system calibration setups
• Digital communication link power management

Procurement Notes

Verify the specific datasheet revision to confirm pinout definitions and TTL voltage levels required for operation. Ensure the host controller output matches the specified logic thresholds. Confirm connector gender and mating compatibility with existing SMA infrastructure before integration into the assembly.

Selection Notes

Select this model when digital programmability is required over manual adjustment. The 63 dB range suits high-dynamic-range testing. Verify that the 200 MHz lower frequency limit aligns with the application spectrum, as it does not support DC or baseband frequencies below this threshold.

Part Context

This component belongs to the Pasternack PE70A series of variable attenuators. It utilizes absorptive technology typical for broadband performance. The module format allows for easy integration into rack-mounted or benchtop instrumentation frames compared to discrete cable assemblies.
